4.1.2.1 Operation

Operation4-Funktionsbeschreibung PNOZ ml2p

The link module PNOZ ml2p is used to safely transfer the input informa­tion from decentralised modules to the safety system PNOZmulti.

Funktionen_multi_Basis

The function of the safety system's inputs and outputs depends on the
safety circuit created using the PNOZmulti Configurator. A chip card is
used to download the safety circuit to the base unit. The base unit has
2 microcontrollers that monitor each other. They evaluate the input cir­cuits on the base unit and expansion modules and switch the outputs on
the base unit and expansion modules accordingly.

The LEDs on the base unit and expansion modules indicate the status
of the PNOZmulti safety system.

The online help on the PNOZmulti Configurator contains descriptions of
the operating modes and all the functions of the PNOZmulti safety sys­tem, plus connection examples.

Funktionsbeschreibung PNOZ ml2p_2

Data exchange:

` Communication with the decentralised modules is via a safe data link.
` The link module PNOZ ml2p reads the input information from the de-

centralised modules as part of each cycle and then forwards it to the
base unit.

` At the end of a PNOZmulti cycle, the base unit sends its output data

to its link module. This output data is immediately sent to the decen­tralised modules.

Linking several decentralised modules:

` A maximum of 4 link modules can be connected to a PNOZmulti base

unit.

` A maximum of 4 decentralised modules can be connected to a link

module PNOZ ml2p.

` If a decentralised module receives data intended for a different de-

centralised module that is connected, the data is forwarded without
being processed.

` The safety system should be installed in a control cabinet with a pro-

tection type of at least IP54. Fit the safety system to a horizontal DIN
rail. The venting slots must face upward and downward. Other mount­ing positions could destroy the safety system.

` Use the notches on the back of the unit to attach it to a DIN rail. Con-

nect the safety system to the DIN rail in an upright position so that the
earthing springs on the safety system are pressed on to the DIN rail.

` The ambient temperature of the PNOZmulti units in the control cabi-

net must not exceed the figure stated in the technical details, other­wise air conditioning will be required.

` To comply with EMC requirements, the DIN rail must have a low im-

pedance connection to the control cabinet housing.

Note:

` Information given in the "Technical details" must be followed.

Verdrahtung PNOZ ml2p

` 2 connection terminals are available for each of the supply connec-

tions 24 V and 0 V. This means that the supply voltage can be looped
through several connections. The current at each terminal may not
exceed 3 A.

` Please refer to the technical details for information on the maximum

cable length. Please also read the section entitled "Voltage drop".

` Shielded cable must be used from a cable length of 30 m.
` Pilz pre-assembled cable can be used to connect the decentralised

The max. cable length depends on the voltage drop in the supply voltage
cables. The level of voltage drop is determined by the:

` Cable resistance on the supply voltage cables
` Operating current of the modules
` Load on the modules

To increase the max. cable length, the input voltage can be permanently
increased by the voltage tolerance (see Technical Details).
