DC Joe Posted September 30, 2015 Report Share Posted September 30, 2015 Dear All, I am having Unistream short range DIN mounted I/O modules. LEDs on 2 of 3 modules showing me green - slow blink. In manual - it is written"boot" / can anybody explain what does it mean, and what to do because I/O does not work? Hope you will help me.

s.pratt Posted September 30, 2015 Report Share Posted September 30, 2015 Hello, Is the expansion module attached straight to the CPU? Do you have a BETA CPU? Link to comment Share on other sites More sharing options...

DC Joe Posted October 1, 2015 Author Report Share Posted October 1, 2015 Maybe is problem with cable RJ45 which use UAGXK125 ? What type of cable should be? is it crossover or ? KR Link to comment Share on other sites More sharing options...
s.pratt Posted October 1, 2015 Report Share Posted October 1, 2015 Hello, I believe the problem is you are using a BETA CPU. I have seen this issue occur when an expansion module is connected straight to the CPU, such as you have shown in your configuration. Please ensure the CPU does not say BETA on the side of it.
