CI853 not transmitting
We combination where we have one CI853 and we are communicating through it with 2 MODBUS line (both ports in use) and there is Phoenix serial converter. The card has to be rebooted to get communication working again every now and then. The Rx lights are blinking all the time but Tx will stop blinking at some point and then communication is not working anymore because external system will not get any data from our side. Have you any idea that is there some issue with firmware or do we have wrong settings? SW side (CCB) is happy without any errors so basically everything is going all the way to the CI853 but not further.
Thanks in advance!
Please provide a screen shot of your settings - both for hardware of CI853 and application (MBConnect and MBRead). Do you have any error code of read/write blocks?
My general recommendations in that case:
under MODBUS protocol, connected to CI853 ports, use Poll Time = 0 and
create a logic for cyclic 0-1 at Req input of the read blocks, after Done output of the block - Req:=not (Done) & not (Err)
