Peer-to-Peer Mode Settings

In Peer-to-Peer mode digital and analog signals can be transferred in both directions across a Zlinx 485 link. For successful communication both base modules must be the same model and all expansion modules must be complimentary (e.g. DI to DO, AI to AO) and arranged in the same order on the Local Bus. One is configured as Peer-to-Peer Master and other is configured as Peer-to-Peer slave. It does not matter which one is configured as master. Additionally, Peer-to-Peer Master address MUST match the Peer- to-Peer Slave address (1-255).

Peer-to-Peer Master

To configure the Zlinx 485 Base module for Peer-to-Peer Master mode:

1.Select the Configuration tab.

2.Select the Peer-to-Peer Master option button.

3.Set the Peer-to-Peer Master address from 1 to 255. Please note the Peer-to-Peer Slave address must also match.

4.The Polling Rate box contains the number of seconds between polls by the master. The default value of 1 second is usually satisfactory. The range of values is 0 to 20 seconds. If the I/O points are not updating properly, try increasing the value.

5.The Retry Count box contains the number of attempts that will be made to communicate with the slave device before the module indicates communication has
