Example
The following example shows how the network can be programmed to detect a trip on the input
medium voltage:
● The PLC reads register 'Data from Drive 03', which is programmed to 'Net1 Out Reg 1'
using the procedure above.
● The SOP sets a flag bit that corresponds to a medium voltage low fault, using the following
SOP source code:
;
Network1Flag9_O = MediumVoltageLowFault_I;
● This example uses bit 9 of 'Net1 Out Reg 1', which is Network1Flag9_O, to set the network
flag true if the medium voltage low fault is active.
● The PLC reads the contents of 'Net1 Out Reg 1', bit 9 (Network1Flag9_O) to determine if
a medium voltage fault occured.
