HIMatrix Safety-Related Controller F3 DIO 8/8 01 Manual
Product Description
The safety-related F3 DIO 8/8 01 remote I/O is a compact system in a metal enclosure with 8 digital inputs, 8 digital DO+ outputs (L- ground), 2 digital DO- outputs (S+ ground), and 2 pulsed outputs. The digital outputs DO4+, DO8+, DO4-, and DO8- can also be connected as two-pole connections.
The remote I/O is available in a model variant for SILworX and a model variant for ELOP II Factory; see Chapter 3.2. All variants are described in this manual.
The remote I/O serves to extend the I/O level of HIMax and HIMatrix controllers, and is connected 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 remote I/O is suitable for mounting in Ex-zone 2; see Chapter 4.1.4.
The device 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.
Safety Function
The remote I/O is equipped with safety-related digital inputs and outputs. The input values on the inputs are safely transmitted to the connected controller via SafeEthernet. The outputs are safely assigned their values by the connected controller via SafeEthernet.
Safety-Related Digital Inputs
The remote I/O is equipped with 20 digital inputs. The state (HIGH, LOW) of each input is signaled by an individual LED.
Mechanical contacts without their own power supply or signal power source can be connected to the inputs. Potential-free mechanical contacts without their own power supply are fed via an internal short-circuit-proof 24 V power source (LS+). Each of them supplies a group of 4 mechanical contacts. Figure 1 shows how the connection is performed.
Reaction in the Event of a Fault
If the device detects a fault on a digital input, the user program processes a low level in accordance 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 the corresponding 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 the F3 DIO 8/8 01 system, e.g., on EMERGENCY STOP inputs complying with Cat. 4 in accordance with EN 954-1.
The remote I/O pulses the pulsed outputs to detect the short-circuits and open circuits on the digital inputs. To do so, configure the Value [BOOL] -> system variable in SILworX or the DO[01].Value system signal in ELOP II Factory. The variables for the pulsed outputs must begin with channel 1 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 created:
1. Cross-circuit between two parallel lines,
2. Improper connections of two lines (e.g., TO 2 to DI 3),
3 . Earth fault of a line (with earthed ground only),
4 . Open-circuit or open contacts, i.e., including when one of the two EMERGENCY STOP switches mentioned above has been engaged; the FAULT LED blinks, and the error code is created.
For more information on how to configure line control in the user program, refer to the HIMatrix Engineering Manual (HI 800 101 E).
Safety-Related Digital Outputs
The remote I/O is equipped with 8 digital outputs DO+ (ground L-) and 2 digital outputs DO- (ground S+). The state (HIGH, LOW) of each output is signaled by an individual LED.
At the maximum ambient temperature, the DO+ outputs 1...3 and 5...7 can be loaded with 0.5 A each, and DO+ outputs 4 and 8 can be loaded with 1 A or with 2 A at an ambient temperature of up to 40 °C.
At the maximum ambient temperature, the DO- outputs 4- and 8- can be loaded with 1 A each or with 2 A at an ambient temperature of up to 40 °C.
The digital outputs DO4+, DO8+, DO4-, and DO8- can be connected as one-pole or two-pole switching connections. The remaining outputs are only set up for one-pole switching connections.
With one-pole switching outputs, ensure that the system's L- ground from the corresponding channel group is used for the DO+ outputs and the system's S+ ground is used for the DO- outputs; see Table 17. The S+ ground is limited by the system to a maximum current of 8 A and is obtained from the 24 V voltage connection.
The external wire of an output is not monitored; however, a detected short circuit is signaled.
With two-pole switching outputs, the L+ switching output DO4+ must be connected to the L- switching output DO4- and the L+ switching output DO8+ to the L- switching output DO8-. This type of connection must be set via the DO2[xx]. Two-Pole system parameter.
During two-pole operation, a line diagnosis is performed to detect potential external short-circuits to L+ and L-. Time on delay is required to detect external short-circuits with an inductive or capacitive load or a lamp load. This delay can be configured using the Time on delay system parameter. In the range of 0...30 ms, the value can be set in steps of 1 ms.
CAUTION
For connecting a load to a one-pole switching output, use the corresponding Lground of the respective channel group (two-pole connection) to ensure that the internal protective circuit can function.
Reaction in the Event of a Fault
If the device 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 device occurs, all digital outputs are switched off.
In both cases, the device activates the FAULT LED.
The error code allows the user to configure additional fault reactions in the user program.
Pulsed Outputs
The 2 digital pulsed outputs can be used for line control to detect short-circuits and open circuits on digital inputs, e.g., on an EMERGENCY STOP button complying with Cat. 4 in accordance with EN 954-1.
Pulsed outputs must not be used as safety-related outputs (e.g., for activating safety-related actuators)!
