Set the number of reading data. 1 to 20 User
[Controls]
(1) A part for the number of reading data of the control data specified with (S1+1) of
data since the device specified with (S2) in the target CPU (n1) is stored to since
the word device specified with (D1) of the self CPU in the Multiple CPU system.
(2) Figure specification of the bit device is possible for (S2) and (D1). However, figure
specification is 4 figures and a start bit device number is only the multiple of 16. It
becomes MULTI-COM.ERROR (Error code: 4353) when other values are
specified.
(3) Data can be read from device of the Motion CPU outside the range in the PLC
CPU that executes this instruction like a motion register (#) etc., by setting (S2) by
a character sequence " ".
(4) D(P).DDRD instruction accepting and normal/abnormal completion can be
confirmed with the complete device (D2) or status display device (D2+1) at the
completion.
(a) Complete device
It is turned on by the END processing of scan which the instruction
completed, and turned off by the next END processing.
(b) Status display device at the completion
It is turned on/off according to the status of the instruction completion.
• Normal completion : OFF
• Abnormal completion : It is turned on by the END processing of scan
which the instruction completed, and turned off by
the next END processing.
(Error code is stored in control data (S1+0:
Complete status).)
