Voltage measurement (U)Voltage measurement is possible on all U-I-R inputs. The voltage to be measured is connected be-tween an input terminal for voltage (see connection diagram) and a ground terminal. The signal mustnot be carrying external potential!The two measurements 0(0.2)...1 V and 0(2)...10 V are selected via the software.The maximum voltage without damage is < 24 V, but the displayed range is limited to 10 V and theinternal resistance Ri of the input is > 50 kΩ.

Current measurement (I)With external resistance connected in parallel to the voltage input, current measurement is possibleon all U-I-R inputs. The signal must not be carrying external potential!

Potentiometer measurementPotentiometers are connected to the U, ground and +5 V terminals.To avoid overloading the reference output, the potentiometer value should be at least 2 kΩ. Potenti-ometers can be used on all U-I-R inputs.

!Note►The +5 V voltage output (terminal 48) is not protected against short circuit! So you must check that the

potentiometers are connected correctly before start-up.

The maximum pulse frequency may be up to 15 Hz. To ensure that switching contacts are recor-ded correctly, a de-bounce time of 20 ms is used. The pulse is recorded on the falling edge and maybe present for an unspecified length of time.The internal counter value of the station is queried in every cycle. The totalling to the actual countervalue is performed in the software after 30 seconds at the latest by the processor of the station. Theformat enables counter values up to 67,108,864 to be represented with a resolution of 1.

For every digital input, setting soft-ware parameters can be used to select individually whether it is used as an alarm or a status value. The inputs are connected between the input and ground terminals.The bit is 0 for an open contact and 1 for a closed contact. The station applies a voltage of 13 V to theterminal, and a current of approximately 0.4 mA flows when the contact is closed. At MFA 58 (frommicroprogramme index “B”), short-term changes of min. 30 ms are stored temporarily between thestation queries and processed during the next cycle. This is recommended for applications with push-buttons, step-switches, etc.



The inputs of the MFA 52 (terminals 10…18) and MFA 59 (terminals 52...60) are preferable for statusreports.

Digital outputsNumber of outputs 8× 0-IType of outputs RelayLoad on outputs 250 V~/2 A (resistive load)

)Note:The following are not admissible: mixed connections for power circuits, different phases (L1/L2) or differ-ent voltage ranges (low voltage)!

With the modu200 AS, 6 digital outputs can be actuated directly. Real feedbacks are only possible via digital inputs.

Analogue outputsNumber of outputs 2Type of outputs 0...10 V=, max. 10 mA (source) or

2…10 V=, max. 10 mA (sink)

)Note:The outputs are not protected against external voltage!

With the modu201 AS, a total of 2 analogue signals can be output directly. The output voltage is takenfrom between the corresponding output terminal and a ground terminal.

Clock and battery conceptA Real Time Clock (RTC) is integrated into the modu201 AS for the time programmes. When operat-ing for the first time, the date, time and changeover between summer/winter time must be checkedand adjusted if necessary.A pluggable lithium button-cell battery (type CR2032) ensures that, if there is a power failure, the userdata (CASE Engine data), parameterised time programmes and historical data (HDB) are retained inthe SRAM. The battery enables the data to be retained and the Real Time Clock to be operated with-out a power supply for at least 3 years from the production date of the AS. When the power returns,the AS will check the consistency of the data and start the communication.It is recommended to store the user data in a user PROM, as this strengthens the security againstdata loss. The user PROM can be programmed using a commercially available device and then beinserted directly into the station.

Technical data for the battery:Type CR2032 lithium button-cellNominal voltage 3 VCapacity 210 mAhDimensions 20 mm × 3.2 mm

Replacing the batteryShould it be necessary to replace the battery in the course of the operating time, this may only beperformed by qualified personnel!

User programThe modu201 AS contains a fast operating program. It reads in all inputs, processes the parameter-ised modules, updates the outputs and handles the necessary communication with other ASs and vis-ualisation PCs via novaNet.The modu201 AS contains a total of 256 machine fine addresses (MFA) for the parameterisation withCASE Engine. In general, MFAs 0…59 are used for the HW addressing and MFAs 64…255 for theSW addressing. MFAs 60…63 are reserved service addresses and are for internal usage.All user programs can be read in/out from any novaNet connection. The data is retained in the bat-tery-supported SRAM, even if there is a power failure. Additionally, the data can be stored in a persis-tent user memory (user PROM). This ensures a very high degree of data security.



Memory structureThe AS has RAM totalling 4 Mbits, divided into 3 sections of 1 Mbit each. The RAM, the microprog-ramme memory and the HDB memory. Each of these areas is divided into 256 machine fine address-es (MFA) of 128 double words (DW) of 32 bits each.The RAM is used to process the loaded application data via CASE Engine and can be parameterised(reading and writing). During the initialisation of the AS, all the stored user data is loaded automatical-ly from the User PROM (if this exists).The microprogramme RAM is reserved for the internal use of the current microprogramme and cannotbe overwritten.The HDB memory (historical data base) is used to save and reproduce digital and analogue values. Ahistorical entry of an MFA is parameterised in CASE Engine and requires a total of 72 bits incl. dateand time. It is possible to save a total of 14,336 historical entries in an AS (ring memory). This is divided into 4 blocks of 3584 entries each.

Block 1: 3584 pieces of digital information in MFAs 0-127Block 2: 3584 pieces of analogue information in MFAs 0-127Block 3: 3584 pieces of digital information in MFAs 128-255Block 4: 3584 pieces of analogue information in MFAs 128-255

Time programmes and calendarsThe AS has a special area within the RAM that can hold a total of 320 time commands. The parame-terisation of the schedules is performed via the management software or the manual operating unit.On the level above the individual time programmes there is a yearly table that can be configured for 2years (even/odd year number).

Summer- and wintertimeThe automatic changeover for summer- and wintertime is a part of the automation station and can bechanged or deactivated using parameterising software or a manual operating unit. The factory settingis for the changeover for summer- and wintertime to be on the last weekend of March and Octoberrespectively, from Saturday to Sunday.

Manual operating unitThe modu240 (EY-OP240F001) operating panel is available as an accessory for the modu201 AS. Itis connected directly via the RJ-45 socket. The operating panel enables data from the AS (with theexception of the HDB) to be processed, e.g. reading measured values, alarms and status, changingsetpoints, outputting positioning commands and changing schedules.

Starting up the ASWhen the power supply is being connected, the protective earth must also be connected with the ter-minal provided (protection class I). The work must always be carried out when the system is discon-nected from the electrical supply!The AS has LED indicators for the operating voltage and the communication. The green LED lightsup continuously to indicate the “ON” operating status for the AS, while the yellow LED flashes to indi-cate “Send” telegram traffic on the novaNet.Before it is connected to the novaNet, every station must receive a unique address between 0 and28671. This address is binary coded manually via the 16 DIP switches (under the housing cover).

)Note:In connection with a BACnet application (moduNet300, EYK220, 230, 300), the station coding must bewithin the range from 0 to 4194.

Example of a setting: AS number 102551 + 2 + 4 + 8 + 2048 + 8192 = 10255 (Even Parity; Off)The parity switch is set so that the number of switches set to “ON”, including the parity switch, is aneven number.If the parity is set incorrectly, the yellow “Send” LED goes out. No communication with the AS (CASEEngine, management level) takes place on the novaNet.In principle, the application data is read in via CASE Engine. The communication is performed via theSAUTER novaNet system bus at terminals a and b. The programming can be performed while data isbeing transferred.So as not to reduce the communication speed of other novaNet subscribers, the station can be dis-connected from the novaNet for the programming period and the parameterising PC connected local-ly. After the data transfer, the data is active immediately.

InitialisationThe initialisation is performed by short-circuiting the two “Ini” half-moon buttons (under the housingcover) for 1-2 seconds. The effect of this is that the station deletes the entire RAM and loads all theuser data from the User PROM (if this exists) in order to restart the controlling and regulation func-tions under defined starting conditions.If no user PROM exists, all the user data (CASE Engine Plan, time programmes, HDBs) are deletedafter an initialisation!An initialisation enables you to reload the automation station directly with CASE Engine data. For this,the CASE Engine data must have been previously stored on a PROM and implemented in the auto-mation station.
