Communicating CI867 as a slave with Yokogawa DCS as a Master
During testing "MODBUS Time Out" Error occurred. We have checked all settings of CI867 and at Gateway side.
Please suggest whether there is something wrong with setting of CI867 or gateway or is there any compatablity issue of Moxa gateway with CI867 (when CI867 used as slave), Please provide solution to communicate CI867 as slave with Master.
In CI867 setting tab in CBM We haveselectedthe 'Slave Enabled' option 'yes'

Check if you could establish a communication with data exchange of the send Modbus Simulator.If this is working use the same settings for connection with your used Modbus partner.The use of your "MOXA gateway" should work transparent by correct configuration of this gateway as we understand.
Please check manual of this device and contact the vendor of this device to get the correct information for this.

i would say also check the hardware configuration , end terminators , baud rate setting..etc
also try to send simple massage first
good luck
I have the same requirement as above for one of my project. I would like to make the communication between the CI867 as modbus rtu slave and DCS system as a master using the MOXA 3280 gateway. I would like to know the details of the settings to be inside the control builder & MOXA converter.
thanks in advance.
