Re: Scapack470 Modbus slave

Hello Noel,

 

When you wrote "PLC" I presume that you mean a SCADAPack x70 type RTU.  The comments below depend on that. Also, you did not state whether you require Ethernet or serial interface. These comments presume that either might be needed.

 

To allow an external device to communicate with an x70 SCADAPack via Modbus requires a few steps be performed, to configure the desired objects with Modbus addresses and configure the port.

 

1) While OFFLINE, right-click on the SCADAPack x70 Controller DeviceDTM and open the Additional Functions menu

2) Select Project Settings and ensure that Modbus IP Servers OR Modbus RTU Server is selected 

NOTE: This feature is enabled by default, so we're just double-checking here...

 

3) On the main Configuration - SPx70 Controller tab, select the Objects tab, then Object Configuration

4) Expand the list of Analog, Digital and Counter objects and open an object that will communicate with the polling device.

5) Select the Modbus tab, enter a Modbus register and data type. Eg for a counter input you might enter 40001 and UINT.

6) Perform this same step with all other objects that must communicate via Modbus.

7) If desired to perform any scaling this can be done on the Basic tab. (eg for analog inputs)

NOTE: if configuring multiple items in a row, you can use the Next > button to move quickly between them.

8/ Once done, press Apply to accept the edits

 

9) Change to the Configuration tab, select the desired Ethernet or serial port and configure it appropriately.

10) Expand the Modbus section, select Server, and set the Unit Identifier (Station address) as required.

11) Apply these changes made to the RTU.

12) Save the configuration, go Online, then Write the changed configuration to the RTU
