Messaging Telephone Number Format - Siemens SIMATIC S7-200 System Manual

Messaging Telephone Number Format

The Messaging Telephone Number is a structure which contains the information needed by the
Modem module to send a message. The Messaging Telephone Number is an ASCII string with a
leading length byte followed by ASCII characters. The maximum length of a Messaging Telephone
Number is 120 bytes (which includes the length byte).
The Messaging Telephone Number contains up to 6 fields separated by a forward slash (/)
character. Back-to-back slashes indicate an empty (null) field. Null fields are set to default values
in the Modem module.
Format: <Telephone Number>/<ID>/<Password/<Protocol>/<Standard>/<Format>
The Telephone Number field is the telephone number that the Modem module dials when sending
a message. If the message being sent is a text or SMS message, this is the telephone number of
the service provider. If the message is a numeric page, this field is the pager telephone number. If
the message is a CPU data transfer, this is the telephone number of the remote device. The
maximum number of characters in this field is 40.
The ID is the pager number or cellular telephone number. This field should consist of the digits 0
to 9 only. If the protocol is a CPU data transfer, this field is used to supply the address of the
remote device. Up to 20 characters are allowed in this field.
The Password field is used to supply the a password for messages sent via TAP if a password is
required by the service provider. For messages sent via UCP this field is used as the originating
address or telephone number. If the message is a CPU data transfer to another Modem module,
this field can be used to supply the password of the remote Modem module. The password can be
up to 15 characters in length.
The Protocol field consists of one ASCII character which tells the Modem module how it should
format and transmit the message. The following values are allowed:
1 -- Numeric paging protocol (default)
2 -- TAP
3 -- UCP command 1
4 -- UCP command 30
5 -- UCP command 51
6 -- CPU data transfer
The Standard field forces the Modem module to use a specific modem standard. The standard
field is one ASCII character. The following values are allowed:
1 -- Bell 103
2 -- Bell 212
3 -- V.21
4 -- V.22
5 -- V.22 bit
6 -- V.23c
7 -- V.32
8 -- V.32 bit
9 -- V.34 (default)
The Format field is three ASCII characters which specify the number of data bits and parity to be
used when transmitting the message. This field does not apply if the protocol is set to numeric
paging. Only the following two settings are allowed:
8N1 -- 8 data bits, no parity, one stop bit (default)
7E1 -- 7 data bits, even parity, one stop bit
