Appendix A
Communication
This appendix describes how to establish ECA communication with a supervisory
control system.
A.1 Communication setup
The information below facilitates the communication setup.
• Serial communication interface RS485 (point to point or multidrop) or RS232
(point to point) is available. A screened twisted-pair cable is to be used. See
"Communications signal wiring, RS485", on page xxxiv.
• The available protocols are COMLI and MODBUS RTU, see "COM Setup",
• The parity must be set to Odd (fixed) in the supervisory system.
• The baud rate may be set between 1200 and 38400 baud, see "COM Setup", on
• All ECA controllers connected to the supervisory control system (Master) are
Slaves.
• Each ECA controller in a network must be set to a unique communication
identity number between #1 and #247, see "COM Setup", on page cxc.
