Modbus MOXA E2212

1

Hello, I want to integrate a Modbus in OPENHAB.

The device is a MOXA E2212

The modbus addresses are the following.

ioLogik E2212 Modbus Mapping
0xxxx Read/Write Coils (Functions 1, 5, 15)

Reference Address Data Type Description

1xxxx Read Only Coils (Function 2)

Reference Address Data Type Description
10001 0x0000 1 bit CH0 DI value

I have configured the following:

modbus.things

Bridge modbus:tcp:garten [ host="192.168.0.12", port=502, id=1 ] {
    Bridge poller coils [ start=0, length=4, refresh=1000, type="coil" ] {
		  Thing data 12_0[ readStart="0", readValueType="bit", writeStart="0", writeValueType="bit", writeType="coil" ]
      Thing data 12_1[ readStart="1", readValueType="bit", writeStart="1", writeValueType="bit", writeType="coil" ]
		  Thing data 12_2[ readStart="2", readValueType="bit", writeStart="2", writeValueType="bit", writeType="coil" ]
		  Thing data 12_3[ readStart="3", readValueType="bit", writeStart="3", writeValueType="bit", writeType="coil" ]	
    }

	 Bridge poller discreteInputs [ start=0, length=4, refresh=1000, type="discrete" ] {
      Thing data di0 [ readStart="0", readValueType="bit" ]
      Thing data di1 [ readStart="1", readValueType="bit" ]
      Thing data di2 [ readStart="2", readValueType="bit" ]
		  Thing data di3 [ readStart="3", readValueType="bit" ]
    }
}

and

modbus.items

//DO 
Number Moxa_IO_12_0  { channel="modbus:data:garten:coils:12_0:number" , autopudate="true"}
Number Moxa_IO_12_1  { channel="modbus:data:garten:coils:12_1:number" , autopudate="true"}
Number Moxa_IO_12_2  { channel="modbus:data:garten:coils:12_2:number" , autopudate="true"}
Number Moxa_IO_12_3  { channel="modbus:data:garten:coils:12_3:number" , autopudate="true"}

//DI
Contact Moxa_Garten_DI0  { channel="modbus:data:garten:discreteInputs:di0:contact" , autopudate="true"}
Contact Moxa_Garten_DI1  { channel="modbus:data:garten:discreteInputs:di1:contact" , autopudate="true"}
Contact Moxa_Garten_DI2  { channel="modbus:data:garten:discreteInputs:di2:contact" , autopudate="true"}
Contact Moxa_Garten_DI3  { channel="modbus:data:garten:discreteInputs:di3:contact" , autopudate="true"}

but it does not work. the values ​​are not updated and are not displayed. what am I doing wrong?

Have you looked at the logs?

3

I have not found any logging in the error. I recently switched to OPEN HAB.

4

This ist openhab.log wenn refresh a IO of the modbus

2019-04-11 10:22:41.159 [WARN ] [rest.core.internal.item.ItemResource] - Receive d HTTP POST request at ‘items/Moxa_IO_12_1’ with an invalid status value ‘ON’.

Now i change from Number to Switch

Switch Moxa_IO_12_0 { channel=“modbus:data:garten:coils:12_0:switch” , autopudate=“true”}
Switch Moxa_IO_12_1 { channel=“modbus:data:garten:coils:12_1:switch” , autopudate=“true”}
Switch Moxa_IO_12_2 { channel=“modbus:data:garten:coils:12_2:switch” , autopudate=“true”}
Switch Moxa_IO_12_3 { channel=“modbus:data:garten:coils:12_3:switch” , autopudate=“true”}

But it still does not update

Reading is now and will be updated but the writing of the exit is not yet.

Please try to format your messages better with code fences. It’s much easier to read.

I still suggest you to get familiar with different logging levels. See the troubleshoot section in modbus binding documentation.
