Figure 12 . GPL Cycle Time vs. Amount of GPL Data.
To calculate the amount of GPL data (in bytes) use the
following equation:
GPL Data = (QTY
Bit
* 1 byte) + (QTY
Word
* 2 bytes) + (QTY
FP
* 4 bytes)
Where:
GPL Data = Total Quantity of GPL Data configured for the Network
QTY
Bit
= Total number of bit type variables (Digital Inputs, Outputs and
Control Relays)
QTY
Word
= Total number of word type variables (analog inputs, outputs,
shared registers)
QTY
FP
= Total number of shared floating point registers
For example, consider a GPL configuration as shown in Table
7 , which lists the amount and types of data each of four
Regents are configured to output to the GPL Network.
