02h
Read Input Status (Coils) Command
Use function code 02h to read bits as individual coil values. The coil method increases data
size and may require multiple polls to completely read one device, but single binary values
placed in one coil greatly simplifies binary state determinations at the Scada master. Use
the 02h coil address provided in the status bit table above to collect data.
