Discrete Output Point Object

The discrete output point objects are part of the device profile
Discrete universal I/O device.
The samosPRO system does not permit direct influencing of the security-oriented output ter-
minals. Instead, up to 400 databits can be specified. In this way, it is possible to use the
input
data blocks
1 to 5
in samosPLAN5+ 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 edi-
tor of samosPLAN5+. The following figure shows an example:

ATTENTION
Check your application thoroughly for correctness!
Because the samosPLAN5+ 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 con-
figured via the logic editor in samosPLAN5+.
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
controls whether the gateway data bit is set or not. The specified value is controlled by in-
stance attribute 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. 103] 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. 103] 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. 103] 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. 103] 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. 103] is already linked to an active connection to a PLC.
