CP 1243-8 IRC
118 Operating Instructions, 02/2018, C79000-G8976-C385-03
The connection establishment is configured in the "Security > VPN > Optional settings"
parameter group with the parameter "Connection type".
●
With this parameter you set the interval at which the CP queries the configuration on the
SINEMA RC Server.
Note that with the setting 0 (zero) changes to the configuration of the SINEMA RC Server
may result in the CP no longer being capable of establishing a connection to the
SINEMA RC Server.
●
The two options of the parameter have the following effect on the connection
establishment:
– Auto
The module establishes a connection to the SINEMA RCServer. The OpenVPN
connection is retained until the connection parameters are changed by the SINEMA
Remote Connect Server. If the connection is interrupted, the CP automatically re-
establishes the connection.
If the connection parameters are changed by the SINEMA Remote Connect Server,
the CP requests the new connection data after the update interval configured above
has elapsed.
– PLC trigger
The option is intended for sporadic communication of the module via the SINEMA RC
Server.
You can use this option when you want to establish temporary connections between
the module and a PC. The temporary connections are established via a PLC tag and
can be used in servicing situations, for example.
●
PLC tag for connection establishment
If the option "PLC trigger" is selected, the module establishes a connection when the PLC
tag (Bool) changes to the value 1. During operation the PLC tag can be set when
necessary, for example using an HMI panel.
When the PLC tag is reset to 0, the connection is terminated again.
You will find the range of functions of the device for SNMP in the section SNMP (Page 175).
If the security functions are enabled, you have the following selection and setting options.
