7.3 I/O Module Setting

PMC-5151 allows connections to ICP DAS M-7000 modules. It also supports standard Modbus RTU or Modbus TCP I/O modules. The I/O

Module Setting page allows user to add Modbus RTU or Modbus TCP I/O modules that are connected to the PMC-5151 to the list. After the module is added, it allows to set up the configuration of the I/O module. The setting page is shown as below:

Figure7-26 : I/O Module Setting Page

The following section will give more information how to add and complete settings of Modbus RTU I/O modules and Modbus TCP I/O modules. After all settings are completed, click “Save” button to save the changes.

Please Note:

1. The COM2 (RS-485) and COM3 (RS-485) interfaces on PMC-5151 allows connections to Modbus RTU I/O modules.

2. The LAN interface on PMC-5151 allows connections to Modbus TCP

I/O modules. For more detailed information of the LAN settings,

please refer to “

6.4 I/O Interface Setting

”.

3. One PMC-5151 allows connections to at most 8 Modbus I/O modules

(including M-7000 modules, Modbus RTU I/O modules and Modbus

TCP I/O modules.)

4. A single I/O interface (COM2, COM3 or LAN) allows connections to at most 16 devices (Power meters and I/O modules); each device requires its own index number. Therefore, if an I/O interface is connecting to both power meters and I/O modules, they will share the same set of the index numbers. For example, if COM2 is connecting to

2 Modbus RTU power meters and already takes the index numbers

No.1 and No.2, the Modbus RTU I/O modules that are going to be connected to COM2 can be only set as No.3 ~ No.16 that are not occupied.
