Description
CIO 2/4 01 is a plug-in module for the modular F60 HIMatrix system.
The module can be inserted in the F60 subrack's slot 3...8 as many times as required. Slots
1 and 2 are reserved for the power supply module and CPU module, respectively.
The module CIO 2/4 01 has 2 counters and 4 digital outputs, which are electrically isolated
from the I/O bus. The status of the output signals is displayed by LEDs located on the front
plate next to the terminal plugs.
The module has been certified by the TÜV for safety-related applications up to SIL 3 (IEC
61508, IEC 61511 and IEC 62061), Cat. 4 (EN 954-1) and PL e (EN ISO 13849-1). Further
safety standards, application standards and test standards are specified in the certificate
available on the HIMA website.
3.1 Safety
Function
If a module fault occurs, the affected outputs are de-energized.
3.1.1 Safety-Related
Outputs
The user program controls the 4 safety-related digital outputs of the module.
Connections are provided on the output terminals for the common ground L-.
If an output channel is overloaded, it is switched off for 10 seconds until the overload is
removed. If all 4 module outputs are loaded with more than 2 A, they are all switched off for
10 seconds.
3.1.1.1
Reaction in the Event of a Fault
If the module detects a faulty signal on a digital output, the affected module output is set to
the safe (de-energized) state using the safety switches.
If a fault in the module occurs, all digital outputs are switched off.
In both cases, the module activates the
FAULT
LED.
The error code allows the user to configure additional fault reactions in the user program.
3.1.2 Safety-Related
Counters
The device is equipped with 2 independent counters with inputs that can be configured for
5 V or 24 V voltage level.
The required voltage level is determined by the user program with the
Counter[0x].5/24V
Mode
system parameter.
Input A is the counter input, B is the count direction input and input Z (zero track) is used to
reset.
Alternatively, all inputs are 4-bit Gray code inputs (with decoder operation)
The following operating modes can be implemented:
Counter function 1 (depending on the count direction input signal)
Counter function 2 (irrespective of the count direction input signal)
Decoder operation with attached absolute rotary transducer
Refer to Chapter 3.4.5 for more details on how to configure the counters.
The safety-related counter has a 24-bit resolution, the maximum counter reading is 2
24
- 1
(= 16 777 215).
