3 Product Description
The X-DI 64 51 standard module is a digital input module and it is intended for use in the
programmable electronic system (PES) HIMax.
The module can be inserted in any of the base plate slots with the exception of the slots
reserved for system bus modules. For more information, refer to the System Manual
(HI 801 001 E).
The module is used to evaluate up to 64 digital input signals. The digital inputs are current
sinking logic for 24 VDC signals in accordance with type 3 specified in the IEC 61131-2.
The standard module can be operated with safety-related modules within one base plate.
The standard module is non-reactive to the safety-related modules. In particular, this
includes EMC, electrical safety, communication to the X-SB and X-CPU modules and the
user program.
Module and connector boards are mechanically coded, see Chapter
3.6.1. This measure
ensures that a safety-related module cannot be replaced by a standard module.
Refer to the HIMax Safety Manual (HI 801 003 E) for more information on the standards
used to test and certify the modules and the HIMax system.
3.1 Safety Function
The module evaluates the digital input signals and provides them to the user program.
The module does not perform any safety-related functions.
The parameters and status for this module must not be used for safety functions.
3.1.1 Reaction in the Event of a Fault
If a fault occurs, the assigned input variables transmit the initial value (default value = 0) to
the user program.
The initial values must be set to 0 to ensure that the input variables transmit the value 0 to
the user program if a fault occurs.
The module activates the Error LED on the front plate.
3.2 Scope of Delivery
The module must be installed on a suitable connector board to be able to operate. If a FTA
is used, a system cable is required to connect the connector board to the FTA. Connector
boards, system cables and FTAs are not included within the scope of delivery.
The connector boards are described in Chapter
3.6, the system cables are described in
Chapter
3.7. The FTAs are described in own manuals.
