Chapter 7 Appendix A: Flow Computer Configurations
The ACiC can use many Electronic Flow Computer Units (FCU’s) to retrieve process variables and some flow
data. This information can be used to control valves and report trend. The universal Modbus interface in the
ACiC provides an interface for an array of electronic FCU’s. In this chapter, some of the possible configurations
will be made available. The configurations in this chapter are examples. The versatility of both the ACiC and the
3 rd party device it is communicating with will often allow for flexible register configurations as well as
communications parameters.
An FCU can communicate with the ACiC serial port or TTL port. When using SMS Text messaging, the serial
port will be occupied by the cellular modem and the FCU will need to be used on the TTL port with a TTL to RS-
232 serial converter. The configurations depicted may be utilized by either port as desired. For use with the
serial port, use cable part numbers A30606VM and C30261VM. For use with the TTL port, use part number PC
232CONV.
