Click the Protocol button to display the dialog box associated with the selected PLC.
Enter the CPU ID. (Match the CPU ID exactly, otherwise leave it completely blank.) Enter Timeout in
seconds. Select the Processor type from the list box.
X31/X32 = Series 30

GE 90/30 CMM Module Setup
The following example shows how a CMM Module Port 1 could be configured.
SNP ENABLE: YES STOP BITS: 1
SNP MODE: SLAVE FLOW CONTROL: NONE
BAUD RATE: 19200 TIME OUT: LONG
PARITY: ODD TURN-A-ROUND: NONE
GE SNP Tag Variables
Format: Gnfffaaa:bb
The leading ‘G’ may be substituted with a ‘%’
n is the memory type of the variable
fff is the data type of the variable
aaa is the address of the variable (range 1--??? Decimal)
:bb is the bit number of the variable (supported only where specified)
Tag variable names are combinations of memory type names and data type modifiers. For example, the
tag name RI is the memory type R and the data type I or Integer. This R register is read as an Integer.
The % sign that precedes each tag name is a requirement of the protocol. Therefore, to read an R
register as an Integer, define the tag variable as %RI. Example, %RI200 is register 200 read as an
integer.
Tag variable names are combinations of register names and modifiers. For example, the tag name RI is
the register name R and the modifier I or Integer. This R register is read as an Integer. The % sign that
precedes each tag name is a requirement of the protocol. Therefore, to read an R register as an Integer,
define the tag variable as %RI. Example, %RI200 is register 200 read as an integer.
When using the Text Display, make sure the tag variable is a %RA. Only 32 characters at a time can be
displayed. Make sure the character length is set to a value of 32 or less. Use the tag editor to modify the
tag attributes.
%RBT is the only word variable that supports bit reading. The format is %RBT:bb where :bb is the bit
number 0-15. For example, %RBT100:06 is register word 100, bit 6. %RBT is read only with no
optional destination ID supported.
