After the above configuration is correctly completed, the collected data can be monitored in the gateway and cloud platform.
6. I/O Module¶
IG502 supports the digital input, pulse counting, digital output, and pulse output functions. In addition, IG502 can remotely read I/O status data or report it to the cloud platform through Modbus TCP. I/O in each mode is defined as follows:
Digital input (Dry contacts and wet contacts are specified based on actual connections.)
The following figure shows the connection modes.
0: 0 V DC to 3 V DC/-3 V DC to 0 V DC
1: 10 V DC to 30 V DC/-30 V DC to -10 V DC (4 mA min)
The following figure shows the connection modes.
A maximum of 3000 Hz pulse signal counting is supported, up to 4294967296. The following figure shows the connection modes.
0: Low level
1: High level. According to the external power output voltage, if no external power supply is connected, no voltage is output. The maximum voltage output is 30 V, 500 mA.
The following figure shows the connection modes.
A maximum of 5000 Hz pulse signal output is supported. The following figure shows the connection modes.
The procedure for configuring I/O and obtaining I/O status data is as follows:
Step 1: Choose “Edge Computing > IO Module > Configuration”, and configure the I/O functions based on the site requirements. The following figures show a configuration example.
The starting value is 0. After power down, the value counted by the power down is retained.
According to the frequency of 5000 Hz, the duty cycle is 50% for the pulse output.
Step 2 (optional): Set the pulse counting and pulse output.
After setting DI to the pulse counting, click Start to count the pulses received by the DI. Otherwise, do not count it. Click Reset to reset the count value to the starting value.
After setting DO to the pulse counting, click Start to output pulses based on the specified output frequency. Otherwise, do not output pulses.
Step 3: Set Modbus TCP Slave.
Turn on the Enable switch to enable the Modbus TCP Slave function. This function allows Modbus TCP Master to read the I/O status of IG502. After you turn on the External Access switch, Modbus TCP Master outside the gateway can read the I/O status of IG502, such as the SCADA software. Set other parameters based on the site requirements. The following figure shows a configuration example.
Step 4: Read the I/O status through Modbus TCP.
Use Device Supervisor to read the I/O status of IG502 in Step 3 as an example. First, add a Modbus TCP controller and set the controller communication parameters based on Modbus TCP Slave.
Then, configure the data to be collected according to the Modbus mapping table. For example, read DI0 Counter Value as an example.
After the configuration is completed, you can obtain DI0 Counter Value.
There are two ways to restore the IG502 to factory settings: hardware factory reset and software factory reset.
Hardware factory reset
- Step 1: After the device is powered on and the ERR light is off, press and hold the RESET key;
- Step 2: When the ERR light is always on, release the RESET key;
- Step 3: After the ERR light goes out, press and hold the RESET key again, and release the RESET key when the ERR light flashes; wait for the ERR light to go out, indicating that the factory reset was successful.
Software factory reset
Choose System Management > Configuration Management, click the reset button and select OK. IG502 will complete the factory reset operation by itself.
