This Modbus Integration Kit for PAC Control R9.3a and higher allows Opto 22 SNAP PAC controllers using PAC Control to communicate using the Modbus Serial RTU, Modbus Serial ASCII or Modbus/TCP protocol.

NOTE: The September 2015 update to this kit (version R9.3a and higher) was a major rewrite including a change to the subroutine’s passed parameters. The new kit is much easier to use. However, upgrading from a previous version of this kit will require modifying your existing PAC Control strategy logic.

The Integration Kit contains Modbus Master subroutines and a Master example strategy, plus a Slave subroutine and a Slave example strategy.

To get started, see form 2164, the Modbus Integration Kit Technical Note. Complete documentation for using the kit is included in the kit’s subroutines.

NOTE: If you are using an older version of this integration kit that does not contain documentation within the strategy and subroutines and you do not want to change kits, see form 2009 for documentation of the older kit.
