3.7.1 Auto Detect
Due to the complex nature of Modbus setups we are providing a function that automatically
detects the attached Modbus device settings. There are several pieces of basic communications
information that once configured, the remaining settings can be automatically detected by
the DCM.
3.7.1.1 Using Auto Detect
A. Configure the basic communications settings. These settings are retrieved from the
connected Modbus device and then entered into the DCM using the below menu items.
1. Baud Rate [Menu Address 5.2.1] – 9600 [DEFAULT]
2. Data Bits [Menu Address 5.2.2] – 8 Bits [DEFAULT]
3. Stop Bits [Menu Address 5.2.3] – 1 [DEFAULT]
4. Parity [Menu Address 5.2.4] – Odd [DEFAULT]
B. Configure the auto detect test settings.
1. Test Address [Menu Address 5.4.1] – 249 [DEFAULT]
2. Test Value [Menu Address 5.4.2] – 840.00 [DEFAULT]
C. Perform the auto detect operation
1. Detect [Menu Address 5.4.3] – No [DEFAULT]
D. Navigate to the above menu address and change the value to Yes. This will start the
auto detection process.
E. Upon completion of the auto detection process, if successful, the display will indicate
“Success” and the updated device settings will be applied. If the auto detection process is
unsuccessful the display will read “Failed - Check Comm Settings” and no device settings
will be changed. For additional information reference section 5.2 Troubleshooting auto-
detect failure.
