8.0 Modbus Setup
The Data Pro is capable of acting as a slave or a master device. There are four (4) serial Modbus ports
and two (2) Ethernet ports. The Ethernet ports are available for TCP/IP Modbus. Serial Modbus ports t
can have multiple devices connected as long as they have a unique address and have the same baud
rate. If no devices have been assigned to a com port, then the Data Pro will treat that port as a Modbus
slave port and will be listening for incoming Modbus requests. A device connected to the Data Pro must
have an internal Modbus map assigned for the Data Pro to sample and store the data to internal
memory. Only Modbus addresses configured in the Data Pro will be saved to memory. Access a
connected device by using the Unit_Id from any of the unused Modbus Ports. For example, if a device
has a slave address of 1, this is the address that the Data Pro uses for communication with the device,
but the device
’s data will be available on Unit_Id 2. Simple configuration can be performed via the Data
Pro, An available PC software application called
‘DataWorks’ is utilized for more advanced
configuration by creating a file that is saved to a USB memory stick then imported to the Data Pro via
the front panel USB port. Five (5) preconfigured Modbus maps pre-configured internally on the Data
Pro:
1. V7 - ( Table 16 )
2. SPS-1500 - ( Table 13 )
3. SCOUT-3000 - ( Table 15 )
4. FIC - ( Table 14 )
5. DL4200
– (Default map) – (
Table 12 )
NOTE:
Data Pro use port 502 for TCP/IP Modbus communication
Any changes to the Modbus setup will cause the Data Pro to reboot.
