JOTA Posted February 16 Report Share Posted February 16 Hello: The first step to connect and IO module is to test communication between both equipments. I downloaded the EX-RC1 communication program that comes with VISILOGIC help, erase the IO that comes and add my IO, compile and transfer to the EX-RC1. While testing, I wired the first 3 inputs and, while online, checked activity at the VISILOGIC and works fine (so communication and configuration seems to be good). Problem happens while testing OUTPUTS. In VISILOGIC i force the OUTPUTS but they do not respond at the IO Module. Diagnostic lights are green and steady, so they indicate everything is fine, but outputs does not work. Any suggestion is appreciated.

MVP 2022 Joe Tauser Posted February 16 MVP 2022 Report Share Posted February 16 Kind of hard to troubleshoot something we can't look at. Upload your program for both the PLC and the EX-RC1 Joe T. Quote Link to comment Share on other sites More sharing options...
JOTA Posted February 23 Author Report Share Posted February 23 Hello Joe: Thanks for your time and effort for helping. Attached is a program without CANBUS communication, some photos (sorry, cannot upload video). This is the way I have tested in the past and it worked . In photos you may look at the installation. The equipment is connected to a power supply, and you can see an EX-RC1 and the IO module. Also you may look at the diagnostic LED that shows correct communication. It should be simple. The EX-RC1 is a CPU. If I connect a CPU to my IO´s I should be able to receive feedback from my inputs and control my outputs. Right now, I can simulate a digital input and it is reflected at the Inputs in VISILOGIC. However, it does not work the other way. When you set an output, you can see it on VISILOGIC, but it does not turns ON on the module. I believe I am doing something wrong. If you find something, please let me know.

AlexUT Posted February 23 Report Share Posted February 23 Your project is empty, so you cannot manage outputs. EX-RC1 intended to be in pair with UNICAN master PLC and than manage outputs from Master PLC. If you use EX-RC1 alone, you have to reset following 3 SBs: Than you can locally set/reset Outputs.

JOTA Posted February 23 Author Report Share Posted February 23 Hello Alex. Thanks for your response. It doesn´t matter if the project is empty. By forcing outputs, the IOS should work. As I said I have tested before and this is a way to assure communication between the EX-RC1 gateway and the IOs. The SB you mention should be at 0 and they all are. Problem has been solved. It was a matter of firmware. Today I received a remote help with UNITRONICS and they update the firmware, and it works. It works without any program. Thanks all for the help, and also for your time and effort. Joaquin Quote Link to comment Share on other sites More sharing options...
