2) Origin Point Input Logic Variable (CHn_ORG_POL@)
Set True when the origin point detector is the negative logic output (B contact) or the
origin point signal input is not used (constantly True).
3) Mark Signal Input Logic Variable (CHn_MARK_POL@)
Set True when the mark detector is the negative logic output (B contact) or the
negative logic should be internally used.
10.1.5 Input Selection Variables
The input selection variable is used to specify the combination of conditions to detect
edges to be captured against the origin point latch input and reference latch input.
1) Reference Latch Input Selection Variable (CHn_REF_SEL!)
This variable is used to specify input signals to detect edges that capture counters. The
condition is either rising or falling edge of either mark signal input or origin point signal
input of the corresponding group channels. The following table shows the list of conditions.
When the signal of the other channel is specified, the input logic of the signal is specified
by the input logic variable of the channel in which the signal is entered.
The two types of PG modules are MCIM-1 and MCIM-2. There are some restrictions in
setting the CHn_REF_SEL! of the MCIM-1 module.
