I am looking for a correct syntax format of HRBCD32 for 2 consecutive Holding Registers with BCD conversion.

I have tried HRBCD32 but it returns incorrect numbers. Is there any special syntax for HRBCD32 ?

Thanks in advance.

I think the documentation may be incorrect, but try HRBCD\_32 (note the underscore)

Ignition 7.8.2

So if you were trying to get the values from say holding register 10 and 11 the syntax would be HRBCD\_3210?
