To use the shared Start or shared Speed Fail Override function, at least one input must be configured to
a value other than “Not Used”. If only one input is configured, the “Configuration Error Log” will indicate a
“Configuration Warning”.
Modbus
If the “Modbus” button is selected, the following screen is displayed:
Figure 8-4. Modbus Configuration Example
The Modbus interface utilizes a master/slave network protocol. The ProTech-GII is always a “Slave”.
The following parameters can be set:
Configure Modbus Settings
Mode:
Select the serial communication mode. Valid values: RS232 or RS485.
Baud Rate:
Sets the serial data rate. Valid values: 19200, 38400, 57600, or 115200 bits/second.
Communication Parity:
Sets the serial parity. Valid values: No Parity, Even Parity, or Odd Parity.
Slave Address:
Unique identifier for this module. If all three modules are connected, each will need
a unique identifying address. Valid values: 1 - 247.
Enable Write Commands:
Set to “Yes” to allow Modbus commands to be written to the ProTech
(e.g. Reset, Initiate Auto Simulated Speed Test). See the Monitor and Control Section in the Modbus
Communications Chapter. When set to “No”, the Modbus interface becomes monitor-only. Valid
values: Yes or No.
