Taylor Remote IO TRIO /CI862 / Current Source Analog Block / AC800M - 800xA upgrade 5.1 to 6.1
Customer has installed version 5.1 AC800M Connect and MOD 300 Connect , it was upgraded from 5.1 to 6.1 . They have two LAN 1 , LAN 2 and CI862
All of the TRIOs have been worked properly so far , but when people did the upgrade two of them can not got to online , showing a hardware status problem it is HW 16#0000001 it is the first TRIO at the cluster it can not go to online and the data from field can be read I mean , signals from field transmitters and also it has configured two outputs ans as you know they use the output holder feature to keep the output just in case a communication or another kind of problem arises. The cluster has 9 TRIOs blocks and the CS Analog IO is the first at the cluster
Off the top of my head we could verify this CS Analog I/O Block and try to connect using the hand held monitor to try to see the configuration, just in case we saw that TRIO has lost the ID address , we should configure it again but to do that sometimes we need to isolate the CS AnalogTRIO
As you know communication goes through shield in , shield out but we could use a 250 ohm resistance to isolate it and configure it .
The question is , Could we put a 250 OHMs resistance at the serial 1 , 2 of this Current Source TRIO to isolate and to configure it and of course the communication with the remaning 8 TRIOs belong to the cluster keeping working and verify some parameter of configuration?
It would be the first step in trouble shooting procedure
Thanks for your support
