Safety Function

The module does not perform any safety-related functions.

The parameters and status for this module must not be used for safety functions.

Reaction in the Event of a Fault

If a fault occurs, 0 is output as rotation speed and the user program retains its last valid process

value for the counter reading.

The module activates the Error LED on the front plate.

Scope of Delivery

The counter module must be installed on a suitable connector board to be able to operate. If a

field termination assembly (FTA) is used, a system cable is required to connect the connector

board to the FTA. Connector boards, sensor selection plug, system cables and FTAs are not

included within the module’s scope of delivery.

The various connector boards are described in Chapter 3.6. the system cables in Chapter 3.7.

The FTAs are described in separated manuals.

Product Description

X-CI 24 51 is a NonSIL counter module intended for use in the programmable electronic system

(PES) HIMax.

The module can be inserted into any of the base plate slots with the exception of the slots

reserved for system bus modules. For more information, see System Manual (HI 801 001 E).

The module is used to count the pulses, to measure the frequency and the rotational speed

and, if defined, to recognize the rotation direction. Two channels are required to use the

recognition of rotation direction function, see Chapter 4.5.4.

Proximity switches in accordance with EN 60947-5-6 (NAMUR) or control circuit devices of

type 3 in accordance with EN 61131-2 can be connected to the counter module. Proximity

switches and control circuit devices may not be operated simultaneously.

It can be operated with safety-related modules and other NonSIL modules within one base

plate. Safety-related and NonSIL modules may not be wired redundantly.

The module is interference-free, in particular, with respect to EMC, electrical safety,

communication to the X-SB and X-CPU modules, as well as the user program.

Module and connector boards are mechanically coded, see Chapter 3.6.1. Coding avoids

installation of improper I/O modules.

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.

Assembly

The input module has 16 safety-related digital inputs 48/120 VAC for contact makers. For

safely detecting a high level on the digital input, the voltage and current thresholds must be

exceeded, see Table 8.

The 8 short-circuit-proof supplies feed 2 supply outputs each (S1 to S8). One supply output

is assigned to each digital input.

The safety-related 1oo2 processor system for the I/O module controls and monitors the I/O

level. The data and states of the I/O module are made available to the processor modules

via the redundant system bus. The system bus has a redundant structure for reasons of

availability. Redundancy is only ensured if both system bus modules are inserted in the

base plates and configured in SILworX.

Safety Function

The module evaluates the digital input signals and provides them to the user program.

The safety function is performed in accordance with SIL 3.

Reaction in the Event of a Fault

If a fault occurs, the module adopts the safe state and the assigned input variables transmit

the initial value 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.

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

Structure

The module has 32 inputs. Each channel measures the input signals through an

internalmeasuring facility.Four short-circuit-proof and current limited supplies feed

eight supply outputs each. Onesupply output is assigned to each input.The 32 inputs

can be used to evaluate the values measured for the proximity switches orwired contacts.

The switching thresholds for generating digital signals can be configured in SILworX.

The processor system for the I/O module controls and monitors the I/O level. The data

andstates of the I/O module are made available to the processor modules via the

redundantsystem bus. The system bus has a redundant structure for reasons of availability.

Redundancy is only ensured if both system bus modules are inserted in the base platesand

configured in SILworX.

Safety Function

Reaction in the Event of a Fault

If a fault occurs, the assigned input variables transmit the initial value (default

value = 0) tothe user program.The initial values must be set to 0 to ensure that

the input variables transmit the value 0 tothe user program if a fault occurs.
