Emerson ROC827 Installing Communication Modules, Example RS-485 Communications Module

ROC827 Instruction Manual

5.2Installing Communication Modules

All communication modules install into the ROC827 in the same way. You can install or remove communication modules while the ROC827 is powered up (hot-swappable), you can install modules directly into unused module slots 1, 2, or 3 (hot-pluggable), and modules are self-identifying in the software. All modules are self-resetting after a fault clears.

Note: The dial-up modem module is not hot-swappable or hot-pluggable. When you install a dial-up modem module, you must remove power from the ROC827.

	hazardous area could result in personal injury or property damage.

Note: You can install communications modules only in slots 1, 2, or 3 of the ROC827. Refer to Figure 5-1.
