S5-95F Addressing
Access to the interrupt PIQ is expressed by the "PB" or "PW" operand identifiers in a statement in
the time-controlled program.
The letter "T" identifies the "Transfer" operation (see Chapter 8).
Figure 6-10. Accesses to the Interrupt PIQ
• Byte-by-byte writing
"PB <byte address>"
Example: Writing signal states to all channels
of an 8-channel digital output module in slot 13
• Word-by-word writing
"PW <word address>"
Example: Writing an analog value to channel 3
of a 4-channel analog output module in slot 5
