Multiple Read NC PLC (MRNP)

This MRNP command transfers several NC/PLC variables in a single register access. This

access method is significantly faster than reading via individual access attempts. The NC/PLC

variables must be included within an MRNP command of the same area.

The areas of the NC/PLC variables are organized as follows:

● General NC data ($MN..., $SN.., /nck/...)

● Channel-specific NC data ($MC..., $SC.., /channel/...)

● PLC data (DB..., MB.., /plc/...)

● Axis-specific NC data on the same axis ($MA..., $SA..)

SWITCH (FOC)

DLGL("Variable ""VarF"" has the input focus.")

DLGL("Variable ""VarZ"" has the input focus.")

DLGL("Any other variable has the input focus.")

Reads several variables

In the variable names, "*" is the separator. The values are transferred to register

REG[Register index] and those following in the order that the variable names

appear in the command.

The following therefore applies:

The value of the first variable is located in REG[Register index].

The value of the second variable is located in REG[Register index + 1], etc.

(Variable name 1*Variable name 2[* ...], Register index)
