Using a P2 PLC. When reading from a drive using the GSR instruction. Does it need to be polled periodically to read the drive running signal, parameter P21.01. Or is there a way to see the drive run status continuously?

You will need to trigger the manual read rung on the GSR instruction, this is edge driven, so it would need to be polled if you wanted it to be updated. Another option is to use an MRX instruction, use the auto poll setting, and read Modbus address 4850 (see gs drive manual chapter 5) to read this status continuously.
Per the help file:
Manual Read: Edge-driven. When Manual Read transitions from OFF to ON, the CPU will send a request to Read the drive parameters that are configured with a Tagname. It will only send one Read request for all of the configured parameters per OFF to ON transition.
