6.2.2.3. Master Message Short Format
In cases where all the arguments P1 – Pn are specified by
numerical values, and not by variable ID numbers, a shortened
form of the master message format may be used. Use the short
format only when backward support for old projects written in short
format is required.
N A M Id1 Id2 C1 C2 P1 P2 . . . Pn S1 S2 CR
To use the short format master message, M (mode) must be set for
the short format, according to the following table.
Mode Code
Broadcast Message
0x0
Polling Message 0x1
Immediate Mode 0x2
Sequential Mode 0x3
Program Mode 0x4
In this format, the V1 and V2 (Variable indicators) bytes are
omitted, as the arguments can only be specified by numerical
values.
N OTE :
The short format is the same format as was used in previous
versions of FlexWorks, in which the specification of arguments
was limited to numerical values.
