[m]MSG[n]:e[.f] [/b] |
m indicates the module to access. If not specified, it is assumed to be 0 (zero), which selects the Resource Manager. If specified, it must be 0 (zero) or the thumbwheel setting for a Logic Processor. |
|
n represents the file number. If not specified, it is assumed to be 0 (zero). If specified, the file number must be 0 - 9999 decimal. |
|
|
e specifies the element number within the String file. It must be 0 - 9999 decimal. |
|
|
.f identifies one of the valid MSG fields. The valid fields for MSG files are listed in the table. |
|
|
b is optional and is normally not used. Specifying the .f fields can access all of the fields of a timer. However, it is possible to use /b to single out a bit in the .PRE or .ACC fields (which are words). For Timer files, the bit number must be 0 - 15 decimal. |
Important! Access to MSG files may degrade the DAServer's performance, due to the extreme size of the MSG file element (56 words each). If accessing only a few MSG elements at one time, performance will not be affected greatly. However, if accessing a few fields of many MSG file elements at once, it may be faster to move the needed fields to an intermediate file (Binary or Integer) and let the DAServer access the intermediate files.
