In the case of a modem connection, before executing write commands via
Modbus, the valid code number (123) must be written to Modbus register
40145. Otherwise, only read commands will be processed. This is used to
prove the legitimacy of the management system.
If an incorrect code number is entered three times via Modbus, this is
recorded as a prohibited access attempt. As the result, an error bit is set and
the control station is dialled by the controller.
6.4.2 Sending SMS if there is a fault on the plant
A modem enables the controller to send an error message to a mobile phone
as an SMS message. As soon as a fault is registered in the device status
register of the controller, an SMS message is sent. This requires modem
access from a provider (SMSC = Short Message Service Centre) which
accepts SMS messages in TAP protocol. The message on the display of the
mobile phone will then read something like this:
'Heating controller EQJW 125 / Device status:
[XXXX] / Note: 0 = no error; >0 = error has occurred'
The value shown for the device status corresponds to the value of SERVice
parameter SP02. The error that has occurred is stored in this value in
encoded form (see Section 6). The SMS Centre usually sends the date, time
and sender's telephone number for this message.
