Name Data type R/W Description
Supply 1 OK BOOL R
The proximity switch supplies are monitored for
overvoltage, low voltage and overcurrent.
TRUE: Proximity switch supply faultless
FALSE: The proximity switch supply is faulty.
Supply 2 OK BOOL R Such as Supply 1 OK
Supply 3 OK BOOL R Such as Supply 1 OK
Supply 4 OK BOOL R Such as Supply 1 OK
Submodule OK BOOL R TRUE: No submodule fault.
No channel faults
FALSE: Submodule fault.
Channel fault (external faults included)
Submodule Status DWORD R Bit-coded submodule status (see 4.3.4 for coding details)
Table 22: Tab I/O Submodule DI32_02 in the Hardware Editor
The proximity switch supplies of the module are short-circuit-proof. The module switches off
the corresponding proximity switch supply if the total current is exceeded (> 200 mA). If the
overload disappears within 30 seconds, the proximity switch supply is switched on again. If
the overload is still present after 30 seconds, the module attempts to restart the proximity
switch supply in intervals of 60 seconds.
Short transient interferences (< 5 ms) do not cause the proximity switch supply to switch
off.
Switching off a proximity switch supply affects all inputs of this group (
Table 10), i.e., the
digital values of these inputs are reset to their initial values. If line monitoring (OC) was
configured, the module also reports an open-circuit in all 8 inputs.
The configured proximity switch supplies are switched on in the STOP-VALID status of the
HIMax controller.
The proximity switch supply outputs of the module cannot be forced and may only be
configured in the Hardware Editor.
The voltage limits of the proximity switch supply outputs are safely monitored by the
module. If an overvoltage, undervoltage or overcurrent occurs, the corresponding status
Supply X OK is set to FALSE.
For supplying a channel, the voltage output assigned to the input must be used (e.g., S1+
with DI1+).
