Issue
Can expansion boards P8UI4AOC and P8UI4AOV be used with a 7718?
Product Line
TAC INET
Environment
- I/NET Seven
- P8UI4AOC Expansion Modules
- P8UI4AOV Expansion Modules
- 7718 Process Control Unit (PCU)
Cause
In addition to the eight inputs and eight outputs on the base card, the 7716 supports the control of additional relay outputs and the monitoring of additional AI, DI, and PI inputs connected via the expansion port. These inputs and outputs occupy point addresses 0100 through 0107. Due to address limitations of the 7718, these expansion boards are not compatible with the 7718.
Resolution
Expansion boards P8UI4AOC and P8UI4AOV cannot be used with a 7718.
Refer to 7718 Process Control Unit - TAC INET - Installation Guide TCON106 regarding supported Expansion Modules.
