When using Modbus address mapping, does the Ignition server poll all entries that are set up, or does it only poll entries that are requested by tags etc.?
We have a system where a few hundred registers are scattered around a range of several thousand PLC registers. It would easier to set up a single big block of registers so that we can request the data using the PLC registers, but not if it's actually going to be trying to read thousands of registers.
