5.3.1
Using the coincidence output function
Each channel has No.1 and No.2 comparison points. Each point individually compares to
the present value (Un\G12 and 13) and outputs the comparison result. (Refer to Table
5.3.)
One comparison point can be set for each No.1 and No.2.
the present value (Un\G12 and 13) and outputs the comparison result. (Refer to Table
5.3.)
One comparison point can be set for each No.1 and No.2.
In this section, I/O numbers (X/Y) and buffer memory addresses are listed for channel 1
and coincidence output No.1. For I/O numbers and buffer memory addresses used for
channel 2 and coincidence output No.2, refer to Section 3.3.1 and Section 3.4.1.
and coincidence output No.1. For I/O numbers and buffer memory addresses used for
channel 2 and coincidence output No.2, refer to Section 3.3.1 and Section 3.4.1.
