Zlinx 485 Modes of Operation

Zlinx 485 systems can operate in Peer-to-Peer or Modbus modes.

Peer-to-Peer Mode

In Peer-to-Peer mode two Zlinx 485 systems provide full serial I/O functionality. In this mode one Base is configured as the master and the other as the slave. (It does not matter which end of the link is the master and which is the slave.) Both Base Modules must be the same model. Analog and digital input signals connected to AI’s and DI’s on one module appear on the corresponding AO’s and DO’s on the other module. Any Expansion modules included in a Peer-to-Peer system must be chosen to be complimentary. For example, if expansion module 1 on one end of the link is a ZZ-4AI (4 analog inputs), expansion module 1 on the other end of the link must be a ZZ-4AO (4 analog outputs.

Modbus Mode

In Modbus mode standard Modbus messages can be sent and received between a Modbus Base Module and a Zlinx 485 system. Data written to output addresses in the Zlinx 485 results in signals appearing on its outputs. Signals connected to Zlinx 485 inputs are converted and stored in Modbus input memory locations and then sent across the link as Modbus messages to the Modbus Base Module.
