Page 7: Diggimec - Nano Hmi With Flag Indicators And Output Relays
DiggiMEC – Nano HMI with Flag Indicators and Output Relays The DiggiMEC is a remote HMI to be used in connection with a WIC1 (version 2) protection relay. (It cannot be used with the predecessor WIC1.) An overview of the elements and connectors can be found here: ╚═▷... - Page 8 A defective cable might impair the internal voltage of the WIC1 and DiggiMEC, and this might affect the capability of the device to operate a trip coil and outputs.

Page 16: Flag Indicator / Output Relays Settings (Diggimec)
Each of these flag indicators is mechanically coupled with a bistable output relay. At any time, the DiggiMEC can toggle the state of an FIx. Note that each FIx is always only set with the rising edge of the assigned signal. - Page 17 All output relay contacts are potential-free. Each relay can be assigned a signal out of the »assignment list«. NOTICE! Whenever the DiggiMEC is not actively used by a human operator we recommend to keep the lid closed. (Depending on the local security directives you might also want to use the sealing option.) This prevents an unintended re-positioning of the flag indicators / output relays.

After that, you should see a menu tree with the same top-level categories as on the DiggiMEC panel. NOTICE! If Smart view complains about a missing “device model” then your Smart view installation is probably older than the WIC1 firmware.
