ioLogik Cellular Micro RTU Controller Planning and Assistance
5-19
Connecting a Modbus/RTU Serial Device
Attached to the ioLogik over a Cellular Network
Scenario: In the water industry, warning systems use both IOs and serial meters to get complete status
information. The ioLogik W5300 has built-in serial ports that support attaching Modbus/RTU serial meters with
RS-232 or RS-485.
Setup Procedure:
Step 1: Start ioAdmin as administrator.
Step 2: Choose the Meter/Sensor tab.
Step 3: Set the serial port parameters: RS-232, RS-485, Baudrate, Stop Bits, etc.
Step 4: Click Modbus TCP Modbus RTU Gateway to choose the operation mode. There are two modes to
choose from: transparent mode and Modbus/RTU mode.
Step 5: Connect the field serial device via the serial port, making sure that the signal wiring is correct.
Step 6: By specifying the W5340’s IP address and the ID of the attached serial devices, you can use the
Modbus/TCP master to query the remote serial device.
NOTE
The Modbus Slave ID for the ioLogik W5300 is fixed at
1, which means that the ID of t
he Modbus/RTU meters
attached to the ioLogik should start from
2 to 247.
Connecting to a SCADA System
Scenario: Most control centers use SCADA systems, such as InTouch, to monitor the status of their entire
system. The ioLogik W5300 with Active OPC server can feed data into the SCADA system. In this situation, the
SCADA system can use its built-in OPC Client/Server architecture to control the system.
Environment
