Tag Variable Table
GE SNPX Tag Variables:
Format: Gnfffaaa:bb\p_?
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)
_? Is the address of the PLC where data will be sent and/or read
Addressing example:
%RUI300 This address will communicate to the PLC address specified as [default]
%IBI25_D This address will communicate with the PLC specified in Reference address D
%AQI100_ABCD This address will not communicate with any PLC because direct PLC addressing
is not allowed
%MBY_abcd This address will not communicate with any PLC because direct PLC addressing is not
allowed and the address must be in all capitals
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.
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.
