IOA addressing issue with IEC60870-5 104 driver in zenOn
Quote:
In the PLC I have three octets for the IOA address. However in zenOn at the addressing information, only IOA1 is available. How do I address e.g. the Double Command (DCO, Type 46) correctly :confused:
in zenOn, all the IOA fields are stored in one field, IOA1. There is a small conversion of the IOAs in the PLC to do, to find the correct addressing information for zenOn.
Example:
in PLC: IOA1 = 196, IOA2 = 135, IOA3 = 0
in hex: C4, 87, 0
in reverse order: 0 87 C4
converted to a decimal number: 34756
IOA1 in zenOn: 34756

Using variable 'Export dBase' and 'Import dBase' it is possible to coverts addressing automatically.
