CHAPTER 2: INSTALL ATION/CONFIGURATION
The control of the "local-remote-off" switch can be set in WinESG parameterization/control panel or by configuring
Modbus RTU register 115. The switch control in WinESG is shown below:
2.2.1.1 Local and Remote Sources Listing
Local sources are defined as hardwire, CP / Modbus RTU or other Modbus RTU modules, and WinESG.
Remote control sources are defined as hardwire, Modbus RTU or other Modbus RTU modules, and Profibus Class 1,
which can be PLC or other Profibus based automation system.
2.2.1.2 Input Configuration
Input can be configured as 1-bit or 2-bit . If set to 1-bit then a single input is used to control the contactor closing
and opening. If set to 2-bit, one input will be mapped to close the contactor and a different input use to open the
contactor.
The same is applicable to Profibus communication. If set to 1-bit , a single ON1 (or ON2) bit is use to turn the
contactor on and off. If using 2-bit, ON1 (or ON2) bit is used to turn on the contactor and OFF bit is use to open the
contactor.
2.2.1.3 Motor Control via Modbus Configuration
Table 2-5 shows the Modbus register mapping of remote source and switch control selections. By setting register 115
to 34 decimal (0x22), it indicates that Modbus is the remote source and also controls the local-remote-off switch.

Fixed Local
Control commands (start, stop, reset etc) can only be issued
by local sources. See section 2.2.1.1 for the local source
listing.
NOTE:
then locals CP / Modbus RTU and WinESG are disabled. If
hardwire connection is set to 2-bit (edge) input
configuration, the locals CP
/ Modbus RTU and WinESG controls are enabled. See
section 2.2.1.2 for detail of 1-bit and 2-bit configurations.
Fixed Remote
Control commands (start, stop, reset etc) can only be issued
by the remote source. See section 2.2.1.1 for the
remote source listing.
If the hardwire connection is set to 1-bit (level)
