TNC 416/TNC 406/TNC 306 Commands 3/2000
3.11.4 Load word accumulator onto Data Stack (PSW) PSW
Abbreviation for PLC Editor: PSW (PUSH WORDACCU)
Execution time [µs] 3.4
Number of bytes 20
Operands: none
Operation:
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)
reserves two Words on the Data Stack. In the event of a stack overflow, an error message will be
issued.
3.11.5 Pull logic accumulator from Data Stack (PLL) PLL
Abbreviation for PLC Editor: PLL (PULL LOGICACCU)
Execution time [µs] 2.2
Number of bytes 16
Operands: none
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.
3.11.6 Pull word accumulator from Data Stack (PLW)
Abbreviation for PLC Editor: PLW (PULL WORDACCU)
Execution time [µs] 2.6
Number of bytes 16
Operands: none
Operation:
The PLW command complements the PSW command. With a PLW instruction, two Words are
copied from the Data Stack into the Word Accumulator. If the stack is empty, an error message will
