EPICS & PLCs Integration

One year and some months ago… 3

After a year… 4

Who owns PLCs at ESS…??? Accelerator Division, Target Division, NSS and Conventional Facilities. Main consumers are (in quantity): – RF local interlocks – Cryogenics Systems – Vacuum Systems – Local Protection Systems – Conventional Facilities Systems ICS does not own by far the majority of the PLCs (but it will provide development effort). But it us who has the standardization capability, almost all of them need to be integrated into the EPICS control system. We are trying to do it together with our stakeholders. 5

Standardization by procurement A PLC hardware Open Call for Tender is about to go out. – We want to procure a framework agreement to select a preferred vendor. – It is ONLY to buy hardware and development software This tender does not cover PSS, TSS and motion controls applications. In any case, selecting a vendor it is not the only aspect of standardization! 7

Cryogenics Integration 12

PLCs in vacuum 13 This is only for analog signals for protection applications. Monitoring signals via serial ports

Modbus vs. s7plc 15 The goal was to measure the capability of exchanging data regarding the exchange rate and the number of channels (connections) used.

Event Correlation Test 16 We are measuring four times: when a Signal is triggered on Timing- IOC. when PLC detects this signal on its digital input. when PLC sends this value to PLC-IOC. when PLC-IOC updates this new value from PLC Wiki PLC

Event Correlation Test (II) 17

Event Correlation Test (III) 18 Similar delay times. Except in the test with minimum PLC cycle time 20ms and PLC push rate 20 ms.

What is ahead….? Finish the OCT and select a vendor Finish the documentation to be provided to the stakeholders Understand how PLC development fit in the overall workflows and select/develop the proper tools for operate and maintain PLC-based controls systems Does UNICOS fits in those workflows? To be seen… Build internal know-how 21
