Rick_PN Posted February 6, 2019 Report Share Posted February 6, 2019 Hi, me again, having problems with Unitronics hardware. This time with module EX-RC1. After 3 months of operation the EX-RC1 module stopped working. CANbus network ceased to work so I had a look at RC1. Only the power LED was lit but I couldn't connect to the module via serial (I tried all bound rates) or canbus. I decided to unplug the module and test it in the "lab". So I connected it to 24 VDC and to serial connection via provided RS232 adapter. Only the power LED is lit and the module is not responding to any "request" via "Communication - PC setting" window in VisiLogic (latest stable version). Then I decided to move all dip-switches (unit ID) to OFF. It made no difference. Then I moved all dip switches to ON -> LEDs for I/O COMM. and Bus COMM started to blink (PWR LED was ON too). After that I was able to establish connection with RC1. I ran "Get OPLC Information " and response is: EX-RC1-BOOT A 2.00 (20). So I suppose this is not "regular" mode? Then I ran PLC Status Get command, response was "Stop, Idle, Idle, Ready, No Error" (unit is in stop mode, flash and memory are idle). I tried to Install operating system (OS V5.04) and all looks like it did the job - status bar for installation was progressing and no error was thrown. But it seems I cannot instruct the module to switch to OS (Run mode), all buttons are grayed out - pic bellow: If I turn module off and on again - there is only PWR LED on and no response from the module (we are back at the start). Its like it can't go to RUN mode. It seems I can't download any program in this "BOOT" mode or factory reset the unit? If I try to download the program I am getting error "Retry binary transmit 1-3 (error0)". How to solve this issue? Quote Link to comment Share on other sites More sharing options...
