Discrete universal I/O device.
The samosPRO system does not permit direct influencing of the security-oriented output terminals.
Instead, up to 400 databits can be specified. In this way, it is possible to use the
input data blocks 1
to 5
in samosPLAN 6 for bit-wise access. The simplest way to control output terminals with a PLC is
by connecting the appropriate gateway bit to an output in the logic editor of samosPLAN 6. The
following figure shows an example:

ATTENTION
Check your application thoroughly for correctness!
Because the samosPLAN 6 only checks for logic-internal connection errors, you have to check the
following aspects systematically yourself:
• Does your application agree with the results from the risk analysis and the avoidance strategy?
• Have all of the applicable standards and guidelines been complied with?
If not, you are placing the machine's operator in danger.
Note that the output terminal is set to
Off
as standard and thus stands for the value “0”. This value is
always used when the controller module is not in
Run
mode or it the output is not configured via the
logic editor in samosPLAN 6.
The standard value of gateway output bits can be configured using attributes 5 and 6.
If there is a loss of connection between the PLC and the controller module, instance attribute 5 con-
trols whether the gateway data bit is set or not. The specified value is controlled by instance attribu-
te 6.
A write request to attribute 3 of instances 1 to 400 is refused if the
Assembly instance 37 [ch. 8.5.2.1, p.
99] is already linked to an active connection to a PLC.
A write request to attribute 3 of instances 81 to 400 is refused if the Assembly instance 138 [ch. 8.5.2,
p. 99] is already linked to an active connection to a PLC.
A write request to attribute 3 of instances 161 to 400 is refused if the Assembly instance 139 [ch. 8.5.2,
p. 99] is already linked to an active connection to a PLC.
A write request to attribute 3 of instances 241 to 400 is refused if the Assembly instance 140 [ch. 8.5.2,
p. 99] is already linked to an active connection to a PLC.
A write request to attribute 3 of instances 321 to 400 is refused if the Assembly instance 141 [ch. 8.5.2,
p. 99] is already linked to an active connection to a PLC.
