3 – Procedure for verifying PLC code in office
1. Print hard copy of PLC tag list with tag name, array name, and hardware address
2. Verify each tag in the PLC code and in EPICS
a. Analog input tags:
i. Force the input tag to some arbitrary value (5)
ii. Verify that the array tag listed on the tag list also changes
iii. Verify that the PV also changes (EDM)
b. Digital input tags
i. Force the input tag to 1 (if it’s currently zero)
ii. Verify that the array tag listed on the tag list also changes
iii. Verify that the PV also changes (EDM)
c. Digital output tags
i. Force the output to 0 or 1, opposite its current state
ii. Verify that the array tag listed on the tag list also changes
iii. Verify that the PV also changes (EDM)
d. Soft tags: PLC -> EPICS
i. Force the tag to change somehow in the PLC
ii. Verify that the PV also changes (EDM)
e. Soft tags: EPICS -> PLC
i. Change PV value to change the PLC tag
ii. Verify that the PLC tag changes
4 d – Reconfigure network settings for production environment
1. Connect PC to PLC with serial cable; establish DF1 connection in RSLinx 2.5 or
newer
2. Set IP address, gateway, DNS, etc for production environment
3. Use RSLinx to set mode to autoconfigure or 100Full? Remove and reinsert
Ethernet module from crate. Verify that RSLinx shows that the card is set
correctly
4. Plug in an Ethernet cable to the module and verify that RSLinx shows 100M/full.
5. Verify that the correct IP address, etc are shown
