3.6 Connection with Superior Monitoring Systems via other than MODBUS RTU Communication
*1: The number of contact output/analog output to control equipement or devices varies depending on the control type or
the number of control units in the system.
For details, refer to the appropriate section for each control type.
・
Interlocking control
→
・
Compressor control
→
・
Schedule control
→
*2: To set up the extension units, the optional small type display unit is required.
For the precautions for system configuration using the extension units or small type display unit, refer to
Precautions for System Configuration
*3: To communicate with the superior monitoring systems, the option unit must be connect to the control unit.
*4: For details on communication with the superior monitoring systems, refer to the following manuals:
・
CC-Link
Energy Measuring Unit Programming Manual (CC-Link) For ver.1 remote device station
Energy Measuring Unit Programming Manual (CC-Link) For ver.2 remote device station
・
