GFK-1115 Chapter 5 PCS Connection Editor 5 - 15

Tables 5-5 and 5-6 provides another overview of the permitted combinations of Panel and PLC
data types. In addition, the address codes and possible limitations on the offset are listed for the
PLC data types.
Note
The statement (offset - 1)%8 calculates the modulo (remainder) of the division
from (offset - 1)/8. This calculation ensures that the address is on a byte
boundary (address -1 is a multiple of 8).
