This document shows examples of system architecture for PC-based I/O control systems and lists Opto 22 products that work together for PC-based control. System examples include:
- Ethernet systems using SoftPAC, a software-based programmable automation controller programmed with PAC Control
- Ethernet systems using the OptoMMP protocol
- Direct control of I/O using no I/O processor (no brain)
- Serial control using a brain and the mistic or Optomux protocol
- High-speed control using the Pamux protocol
The AC7A/B is a stand-alone adapter card that converts RS-232 serial communication to RS-422/485 serial communication, which is directly compatible with the Optomux family of intelligent brain boards.
This document gives instructions for installing the AC7A/B adapter card in an Optomux network in 4-wire RS-422/485 mode with a PC and how to communicate with equipment other Optomux.
