Configuration and operation
4.5 Telecontrol communication (CP 1542SP-1 IRC)
CP 1542SP-1, CP 1542SP-1 IRC, CP 1543SP-1
82 Operating Instructions, 01/2017, C79000-G8976-C426-03
Requirements and necessary information
Remember the following requirements in the CP configuration for the transfer of e-mails:
● Enabling telecontrol communication ("Communication types") parameter group
● Configuring the "E-mail configuration" parameter group (see "Security" parameter group)
To do this, you require the following information:
– Access data of the SMTP server: Address, port number, user name, password
– Email address of the recipient
Trigger: Triggering e-mail transfer
Using the "Trigger" parameter group in the message table, you configure which of the
following events triggers the sending of the e-mail.
● CPU changes to STOP.
● CPU changes to RUN.
● The connection to the partner is interrupted.
● The connection to the partner is re-established.
● A trigger signal is fired.
For the trigger signal to send the e-mail, the edge change (0 → 1) of a trigger bit is
evaluated that is set by the user program. When necessary, a separate trigger bit can be
configured for each e-mail.
If the memory area of the trigger bit is in the bit memory or in a data block, the trigger bit
is reset to zero when the e-mail is sent.
With the "TeleControl Basic" protocol, the following events can be configured as the trigger
of an e-mail:
● Connection establishment to the partner has failed.
● A TeleService session has started.
● A TeleService session has ended.
Include value Transfer the value of a PLC tag with a message
If you enable the option "Include value" in the "Trigger" parameter group, the CP sends a
value for the placeholder $$ from the memory area of the CPU in the message. To do this
enter "$$" as a placeholder for the value to be sent in the message text.
Select a PLC tag whose value will be integrated in the message. The value is entered in the
message text instead of the placeholder $$.
$$ can be a placeholder for data point types with a simple data type up to a size of 32 bits.
