I have a problem with DO802, having exclamatory sign on DO802 in control builder & red mark on card in CB,chk pix
DO802 is an Relay Normally open module, please ensure the connection of DO802 are made as attached document.
Regarding error :- IOError 16#00000002 its an I/O error Error Alarm Medium.
Please use CBM help for
Status bit Value Description and Status Type Alarm/Event Severity.
It seems that your channel has fallen in open loop. As this is an DO module, if you feed any value to the field devices with supported impedance, then you would not get channel error.
The status 16#00000002 is for I/O error. and status 16#00000030 is the XOR of Channel error and I/O warning. without going much into these statuses, if you connect any output device to feed the values (or connect a DI channel, or connect it to multimeter) you will get rid of this channel error.
