Solution for PCDI(Peer Control Data Interface) and SCADA(Supervisory control and Data Acquisition address assignment?


If we gave both PCDI & SCADA address to any one tag and loaded to controller. After loading if u delete that address in particular tag and assign same address to same tag or different tags it wont allow.Pls suggest a solution?


Hi omega,

For using same address use following steps
Step1–>Initially unassign PCDI & SCADA address and load to controller
Step2–>Now assign same address to same tag or other tags
This problem will come when “Online Modification” of controller properties is checked.
