16 Analog Mux Module 16.1 Summary

16.1.1 Features

Analog Mux module receives analog values from 4 channels and outputs the same values to one

port at a time.

１) Desired channels can be selected to be enabled or disabled and get operation status.

２) Different relay ON time can be set by each channel from 0.1 to 1000.0 seconds range.

３) Relay count values can be checked for life expectancy for the relay.

４) Easy control with Auto/Manual mode.

５) Power LED blinks by 0.5 second interval when there’s an error with CPU communication.

６) It is not suitable for current signal use since this module switches analog signals repeatedly.

in the module setup window, AD MUX Channel Setup pops up as below

① Channel Enable/Disable: Select the check box to Enable the channel and deselect to disable.

② Relay On time settings : 0~10000 (0.1 ~ 1000 seconds)

- Click “OK” after the set-up is complete

- Select the entire channels as below and then click to configure the settings all

at once.

Click for the Mux module to be able to operate by the configured settings.

A message “Set value was written to PLC” shows up in the message display window.

Configured values get saved in the flash memory so that even when the power restarts, the

saved settings don’t get changed.

Button reads the current values that has been set from the Mux module

- Save after enabling the entire channels

- Select the entire channels and click to reset the counter.

- Click on the settings windows to have a pop-up window as follows

Select “Yes” button to change to the manual mode and the button on the right hand side

changes to

16.7 Application Program and Example

To use a Mux module, the desired channels should be enabled and the relay ON time should be set.

There are two ways for configuring the module settings.

- When configuring the settings on the RTD settings window of CICON (refer to page 6), there’s no

need to use scan program as below. However, when the modules get swapped, the settings need to

be reconfigured.

- Module settings configuration can be done by using scan program as below.

Whichever method the user chooses, the settings get saved on the internal memory and it stays even

when the power restarts.

Row 0: channels 1,2,3,4 of SP04EAM module get enabled

Row 1: channels 1,2,3,4 Relay ON time get set to 1.5 seconds

Row 2: the settings save request (Y22) gets SET

Row 3: when the settings save completed flag (X22) is SET, the settings save request (Y22) resets

16.8 Installation and Wiring

16.8.1 Installation

１) Installation Environment

• Environmental Conditions

Please install in a dust-proof and water-proof control panel.

Please install it where there is without any continuous shock or vibration.

Please avoid locations that are exposed to direct sunlight.

Please avoid locations with rapid temperature change and condensing environment.

Please install it where the ambient temperature is -10 ~ +65℃.

• Installation

Please be careful not to let any wire scraps into the PLC during drilling or wiring.

Please Install the PLC in an ideal position to operate

Please do not install in the same panel as the high voltage equipment

The distance between the duct and any other modules should be at least 50mm.

Ground it in a location where there’s a decent ambient noise level.

２) Handling Precautions

• Please do not let it drop or give strong impact.

• Please do not remove the PCB from the case since it may cause a malfunction

• Please be careful not to let wire scraps to enter the module during wiring.

• Please refrain from detaching the module while the power is ON

16.8.2 Wiring

１) Caution for Wiring

• Please don’t let the AC surge or induction noise to effect the module by connecting a separate

cable between the module’s external input signal and the alternate current.

• The wire should be selected considering the ambient temperature and the current used. The

minimum thickness of the wire should be AWG22 (0.3 mm2).

• When wiring, if the wire is in direct contact with oil, hazardous substances or devices that

generate high temperatures, it might cause a damage or malfunction.

• Please verify the polarity before applying analog input to the terminal.

• When wiring with high voltage line or power line, the malfunction or failure may cause by

induced failure.

• It is not suitable for current signal use since this module switches analog signals repeatedly.
