Communications Protocol
This menu is located under the Setup Global Parameters
main menu. It allows you to select the Communications
Protocol.
Selectable values: Anafaze (ANA), Allen Bradley (AB),
ModBus RTU (MOD)
Communications Error Checking
This selection allows you to set the data check algorithm
used in the Anafaze communications protocol to Block
Check Character (BCC) or to Cyclic Redundancy Check
(CRC). CRC is a more secure error checking algorithm than
BCC, but it requires more calculation time and slows the
CAS200 communications. BCC ensures a high degree of
communications integrity, so we recommend that you use
BCC unless your application specifically requires CRC.
Also, if using Anascan, ensure that the same error checking
algorithm has been set through the ’scaninst’ program.
Selectable values: BCC or CRC
