7.3 I/O Module Setting
PMC/PMD allows connections to ICP DAS M-7000/DL/IR 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/PMD 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 2 COM Port (RS-485) interfaces on PMC/PMD allows
connections to Modbus RTU I/O modules.
2. The LAN interface on PMC/PMD allows connections to Modbus TCP
I/O modules. For more detailed information of the LAN settings,
please refer to “ 6.5 I/O Interface Setting
”.
3. One PMC/PMD allows connections to at most 8 Modbus I/O modules
(including M-7000/DL/IR modules, Modbus RTU I/O modules and
Modbus TCP I/O modules.)
4. A single I/O interface 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 COM3 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 COM3 can be only set as
No.3 ~ No.16 that are not occupied.
