SRT1016 Wiring mode:

SRT1016 is a 16-channel general-purpose digital input module, and COM1 is the common terminal of the channels corresponding to Input points I 0.0~I 0.7; COM2 is the common terminal of the channels corresponding to Input points I 0.8~I 0.F. Two groups of COM are connected independently according to the type of external input signal. When the type of external input signal is PNP, COM is connected to 0V; When the type of external input signal is NPN, COM is connected to 24V. Each COM group provides two terminals internally connected, allowing users to parallel wires for convenient wiring.

Module Description

SRT1016 is a 16-channel general-purpose digital input module. It also has functions such as filter parameter configuration, module configuration status monitoring, and communication status monitoring. It occupies 2 words for input and 1 word for output (see Table 1-2 for the address table). The module needs to be used with the SRT series coupler, and the IO terminal cannot be used alone; The module functions described in this paper are realized on the premise of normal communication between SRT1016 module and the coupler (1word=2byte).

Note: during module parameter configuration, first set module parameters in the plc initialization program, and then enable the parameter configuration bit of the coupler to make the parameter configuration effective; The second modification of module parameter configuration takes effect only after the module is powered off and restarted once.
