Question

Siemens S7-1200 PLCs also have ________ timer instructions. One of these is the Timer On-Delay instruction (TONR).

Answer 1

Siemens S7-1200 PLCs offer various timer instructions like the Timer On-Delay (TONR), which is used to delay the activation of an output.

Step-by-step explanation:

Siemens S7-1200 Programmable Logic Controllers (PLCs) provide multiple timer instructions for automation purposes. One of the timer instructions available in a Siemens S7-1200 PLC is the Timer On-Delay instruction, identified by the acronym TONR. This instruction is used when a delay is needed before turning on an output. The Timer On-Delay starts timing when the input signal becomes true, and after the preset time elapses, the output becomes true. In addition to TONR, there are multiple other timer types such as off-delay timers and pulse timers which can be employed depending on the control logic requirements.
