PSRmodular system
194 / 232
PHOENIX CONTACT 109241_en_03
Operating principle:
1. The “N
ETWORK_IN” input must be linked to the “OUT” output of the “NETWORK_IN”
function block (see section “NETWORK_IN function block”).
2. The 1- or 2-channel inputs of the “N
ETWORK_IN” block are linked to the 1- or 2-channel
outputs of the base module in the emergency stop chain.
3. The “N
ETWORK_OUT” output must be connected to a 1-channel or 2-channel output.
This output is led to the inputs of the next base module in the emergency stop chain.
4. The local emergency stop signal is connected to the “S
TOP_IN” input. This input affects
the “O
UT” output as well as the “NETWORK_OUT” output.
5. The local reset command (e.g., by the “SWITCH” function block) is connected to the
“R
ESET_IN” input.
6. The “I
N” input can be freely used for other safety enable conditions (group enables,
etc.). This only affects the local “O
UT” output and not the line emergency stop signal. In
this case, the local outputs can only be restarted via a manual reset (R
ESET_IN).
7. The enable signal for the local switch-off conditions is generated with the “O
UT” output.
The output is logic “1” if the “S
TOP_IN” input signal, the “IN” input signal, and the line
emergency stop signal are present.
Parameters
Enable Network Reset If the “Enable Network Reset” option is not selected, after a power up or after triggering the
safety function at the “S
TOP_IN” input, a local reset command must be performed at each
base module in the network.
If the “Enable Network Reset” option is selected, after a power up, it is possible to activate
the network as well as the output (“O
UT”) of all “NETWORK” blocks via a reset button on any
base module.
If the network is interrupted at any base module by the triggering of the safety function, the
following applies:
1. The network as well as the output (“O
UT”) of all “NETWORK” blocks are activated when
the reset button of the interrupted base module is pressed.
2. Pressing a reset button of an uninterrupted base module (safety function not triggered)
activates the network and just the output (“O
UT”) of the “NETWORK” blocks of uninter-
rupted base modules.
Enable Error Out When this parameter is selected, an output (“E
RROR”) is made available which signals that
an error has been detected by the function block.
Global Reset enabled If this parameter is selected, the entire system can be restarted via the reset button of any
base module.
If this option is not selected, all base modules that did not cause the stop can be restarted
from any point in the network, with the exception of the base module that caused the stop.
This module must be restarted with the corresponding reset.
Stop cause Only with PSR-M-B2: if this parameter is selected, the “N
ETWORK_STOP” and “LOCAL_STOP”
outputs are activated and indicate the cause of the stop status. These outputs are logic “0”
if the “O
UT” output is logic “1”.
If a network stop is generated, the “N
ETWORK_STOP” output changes to logic “1”. However,
if the “O
UT” output changes to logic “0” due to the “IN” input or the “STOP_IN” input, the “LO-
CAL_STOP” output changes to logic “1”. The outputs remain until the next network reset
under these conditions.
