Abbreviation for PLC Editor: PSW (PUSH WORDACCU)
Execution time [µs] 1.0 to 1.1
Number of bytes 20

The content of the Word Accumulator can be buffered with the PSW command. For this purpose,
the Word Accumulator is copied into the Data Stack. The content of the Word Accumulator (32 bit)

Operation:
The PLL command complements the PSL command. With a PLL instruction, bit 7 from the current
address of the Data Stack is copied into the Logic Accumulator. If the stack is empty, an error
message will be issued.
