Group C: Multi-Function Terminal Function; Multi-Function Input Selection - Omron 3G3JX User Manual

4-2 Function Mode
<Group C: Multi-function Terminal Function>
The 3G3JX has five input terminals [S1], [S2], [S3], [S4] and [S5]; one open collector output terminal
[P1]; two relay output terminals [MA] and [MB] (SPDT contact); and one analog output terminal
[AM].

Multi-function Input Selection

The five input terminals [S1], [S2], [S3], [S4] and [S5] act as multi-function input terminals, whose
functions can be changed through reallocation. 31 functions are available for allocation.
You can switch the input logic between Sink and Source, and the contact specifications between
NO and NC. (NO [normally open] is allocated by factory default.)

•The terminal with reset allocated is fixed to NO.
•Multi-function input terminal S3 is also used for emergency shutoff input. With DIP switch S8 on
the control PCB turned on, emergency shutoff input works. If a signal is input to terminal S3, the
output is shut off and an error occurs, not through software but only through hardware.
The same two functions cannot be allocated to the multi-function input terminals. If you attempt to
allocate the same two functions to the terminals by mistake, the terminal where you allocated the
function last takes precedence. The previous data is set to "255", and the terminal function is
disabled.
•PTC can be allocated only to input terminal [S5].
•Parameter No. C001 to C005 correspond to input terminals [1] to [5] respectively.
