How to add extension module for PLC FX2-60MR

[presario2100]

If we want to add 1 analog input and 1 analog output extension module, we need to do some setting in the programming software ? or after plug in we can use it directly ? Thanks.

You need to set them up in the software. Tell the analogue units whether they will be current or voltage, then read and write the information to the analogue units. It's pretty standard stuff, if you know the part numbers of the analogue blocks.

Do you place an extension module like the FX-series, so you connect them on the bus. Then it is depending on the kind of module you are using. If you use a FX0N-3A module, the wiring will make the difference between current or voltage. You need to write a programme with FROM and TO instructions to read and write the values. For the FX2N-4AD and 4DA module, you can set some initial settings inside the module for current or voltage, resolution, offset and gain. To do this, and to read and write the values, write a programme with the FROM and TO instructions. For the modular series PLC, like system Q for instance set the correct parameters by the switch settings. Then use or the special function utility or the FROM and TO instructions. Myself prefer the special function utility because this is independent of the PLC scan time. A FROM and TO instruction increases the scan time. For every module in the documentation delivered by the module a short example programme is delivered. succes
