HIMA digital module F7553 Z7306 Ethernet communication module

Description

Z7306 Personnel configuring the HIQuad X hardware must observe the following product-dependent

safety requirements.

Only devices with electrically protective separation from the power supply may be connected

to the system

Only safety-related modules may be used to Z7306 process safety-related tasks.

The conditions of use detailed in the system manual, particularly those concerning supply

voltage and climate, must be observed.

Power must be supplied by power supply units Z7306 complying with SELV and PELV. For the

power supply units, the following applies:

– 24 VDC power supply: The voltage of the power supply units may not exceed 31 V.

– 48 VDC power supply: The voltage of the power supply units may not exceed 62 V.

The requirements for power supply provided through the mains supply are the same as

those applying to power supply units.

Z7306 Product-Independent Programming Requirements

Personnel developing user programs must observe the following product-independent safety

requirements:

In safety-relevant applications, ensure that the safety-relevant system parameters are

properly configured.

In particular, this applies to the system configuration, maximum cycle time and safety time.

3.4.4

Product-Dependent Programming Requirements

The SILworX programming tool must be used for programming the HIQuad X system. The

following requirements for using SILworX must be met.

The application described in the specification must be validated, verified and its proper

implementation must be documented. Z7306 A complete test of the logic must be performed by

trial.

If the user program is changed, all the logic parts affected by the changes must be tested.

A system response to faults must be defined for faults in safety-related input and output

modules in accordance with the application-specific safety-related requirements. These are

for instance fault responses in the user program and the configuration of safe initial values

for variables.

3.4.5

Z7306 Communication

The following requirements for communication of data and to systems must be met.

When implementing safety-related communications between various systems, ensure that

the overall response time of the system does not exceed the worst case response time

permitted for safeethernet or HIPRO-S V2. All calculations must be performed in

accordance with the rules given in Chapter 11.3.

During the transfer of (safety-relevant) data, IT security rules must be observed.

The transfer of safety-relevant data through public or Z7306 publicly accessible networks (e.g., the

Internet, WLAN) is only permitted if additional security measures have been implemented,

e.g., a VPN tunnel and firewall.

If data is transferred through company/plant internal networks, administrative and technical

measures must be implemented to ensure sufficient protection against manipulation (e.g., a

firewall to separate the safety-relevant components of the network from other networks).

Never use the standard protocols to transfer safety-related data.

The communication interfaces must be connected to devices with electrically protective

separation.
