HIMA F3 DIO 20/8 02 - Safety-Related Controller

Description

The safety-related F3 DIO 20/8 02 remote I/O is a compact system located in a metalenclosure with 20 digital inputs and 8 digital outputs. The remote I/O is available in a model variant for SILworX and a model variant for ELOP IIFactory, All variants are described in this manual. The remote I/O serves to extend the I/O level of HIMax and HIMatrix controllers, and isconnected to them via safeethernet.   The remote I/O itself is not able to run a user program. The HIMatrix remote I/Os are not multi-master capable. The device has been certified by the TÜV for safety-related applications up to SIL 3 (IEC61508, IEC 61511 and IEC 62061), Cat. 4 (EN 954-1) and PL e (EN ISO 13849-1).   Furthersafety standards, application standards and test standards are specified in the certificateavailable on the HIMA website.

Safety Function The remote I/O is equipped with safety-related digital inputs and outputs. The input valueson the inputs are safely transmitted to the connected controller via safeethernet. Theoutputs are safely assigned their values by the connected controller via safeethernet. Safety-Related Digital Inputs The remote I/O is equipped with 20 digital outputs. The state (HIGH, LOW) of each input issignaled by an LED. Mechanical contacts without own power supply or signal power source can be connected tothe inputs. Potential-free mechanical contacts without own power supply are fed via aninternal short-circuit-proof 24 V power source (LS+). Each of them supply a group of 4mechanical contacts. Figure 1 shows how the connection is performed. For the external wiring and the connection of sensors, apply the de-energized-to-tripprinciple. Thus, if a fault occurs, the input signals adopt a de-energized, safe state (lowlevel). An external wire is not monitored, but an open-circuit is considered as safe low level.

Reaction in the Event of a Fault If the device detects a fault on a digital input, the user program processes a low level inaccordance with the de-energized to trip principle.The device activates the FAULT LED.In addition to the channel signal value, the user program must also consider thecorresponding error code.The error code allows the user to configure additional fault reactions in the user program. Line Control Line control is used to detect short-circuits or open-circuits and can be configured for theremote I/O, e.g., on EMERGENCY STOP inputs complying with Cat. 4 in accordance withEN 954-1. The remote I/O pulses the pulsed outputs to detect the short-circuits and open-circuits onthe digital inputs. To do so, configure the Value.[BOOL] -> system variable in SILworX andthe DO[0x].Value system signal in ELOP II Factory. The variables must begin with channel1 and reside in direct sequence, one after the other. If the following faults occur, the FAULT LED located on the front plate of the device blinks,the inputs are set to low level and an (evaluable) error code is displayed: • Cross-circuit between two parallel lines, • Improper connections of two lines (e.g., DO 2 after DI 3), • Earth fault of a line (with earthed ground only), • Open-circuit or open contacts, i.e., also if one of the two EMERGENCY STOP switchespreviously mentioned the FAULT LED is being engaged.
