Example: Read coil status FC1

Configuration
Data content Modbus Slave
echolink one reads Address 5 + 6 and copies it into the 6. byte of the output buffer.
Fieldbus output data (echolink one -> SPS)
66 07 00 00 00 00 00 00
1. Byte = Trigger byte (value = 0x66 )
2. Byte = Fieldbus length byte (value = 0x07)
3. Byte = Fieldbus Map Adr 0 (value = 0x00)
4. Byte = Fieldbus Map Adr 1 (value = 0x00)
5. Byte = Fieldbus Map Adr 2 (value = 0x00 )
6. Byte = Fieldbus Map Adr 3 (value = 0x00)
7. Byte = Fieldbus Map Adr 4 (value = 0x00)
8. Byte = Fieldbus Map Adr 5 (value = 0x00)
9. Byte = Fieldbus Map Adr 6 (value = 0x01) see configuration
10. Byte = Fieldbus Map Adr 7 (value = 0x00)
11. Byte ...

In the following example the value in address 6 in the Modbus Master is changed from 0 to 1.
