RS 485 to SCADA

I have Siemens S7 1200, and I want to send data to Experion Honeywell SCADA. On a Siemens side I use RS485, and I convert it to Ethernet using Planet ICS 2105a. I am not sure how to setup Siemens (master or slave) and should Planet be Server or Client? Is there anything I should pay attention in Quick builder configuring variables I want to read in SCADA?
