Query via system
variable
The terminal level of the binary inputs in the basic unit and any installed option are rep-
resented cyclically in the system variables
H483 INPUT LVL
(MOVIDRIVE
®
A) /
H520
INPUT LVL B
(MOVIDRIVE
®
B). In the process, the bits of the H483 system variable
are each assigned to one hardware input.
The assignment of the H483 system variables for MOVIDRIVE
®
A / H520 for
MOVIDRIVE
®
B to the binary input terminals in described in the section "IPOS
plus®
Vari-
ables / Overview of the system variables".
The binary inputs in the IPOS
plus®
program can be queried using the value of the vari-
ables H483/H520. This is useful for querying inputs to be used to transfer a binary-
coded, for example, for selecting a table position.
Binary terminals represented with the higher value bits of variables H483/H520 can also
be queried using a combination of the BMOV and JMP commands. This is the case
when two options are installed at the same time with terminal expansion.
