Controller Address
Set the communications address for the controller. On an EIA/TIA-485 communication network,
each controller must have a unique address. Begin with address 1 for the first controller and assign
each subsequent controller the next higher address.
ALARM
CONTROLLER
ADDRESS ? 1
Selectable values: 1 to 247.
Communications Baud Rate
Set the communications baud rate.
ALARM
COMMUNICATIONS
BAUD RATE ?19200
Selectable values: 9600, 2400 or 19200.
NOTE! Set the baud rate to the same speed in both the controller and the HMI software
or panel.
Communications Protocol
Set the communications protocol. Choose the correct protocol for the software or device with which
the controller will communicate. You must switch power to the controller off, then back on, to make
a change to this parameter take effect.
ALARM
COMMUNICATIONS
PROTOCOL ? MOD
Selectable values: MOD (Modbus
®
RTU), ANA (Anafaze), AB (Allen Bradley).
Communications Error Checking
If you selected the ANA or AB communications protocol, set the data check algorithm for CLS200
communications.
CRC (Cyclic Redundancy Check) is a more secure error checking algorithm than BCC, but it requires
more calculation time and slows communications. BCC (Block Check Character) ensures a high
degree of communications integrity. We recommend BCC unless your application requires CRC.
