12 Important Notes WAGO-TO-PASS® 761
761-217 Telecontrol Module Compact, 8 AI, Web, MODBUS485
Manual
Version 1.0.0
Please send your request for modified and new hardware or software
configurations directly to WAGO Kontakttechnik GmbH & Co. KG.
2.2 Disclaimer
TO-PASS®telecontrol modules communicate using the GSM network (Global
System for Mobile Communication). Exemptions cannot be made for GSM
services used by the TO-PASS®telecontrol modules as they may be exposed to
faults in the service provider’s network. WAGO Kontakttechnik GmbH & Co.
KG has no involvment with these types of problems.
Therefore, WAGO Kontakttechnik GmbH & Co. KG will reject any guarantee for
the implementation of commands transmitted from and received by the TO-PASS®
telecontrol module.
2.3 Firmware Licensing Terms
2.3.1 Firmware with Open Source GPL
The TO-PASS®Compact telecontrol module firmware contains Open Source
software under GPL. According to Section 3b of GPL, we offer you the source
code.
You can obtain the source code with licensing terms of the Open Source software
from WAGO Kontakttechnik GmbH & Co. KG on request. Send your request to
[email protected] with the subject "Open Source TO-PASS Compact".
2.4 Block Rounding for GPRS Connections
The connection to the provider is established separately for each GPRS data
transfer up to Firmware Version 2.31 (approx. 1 ... 2 kBytes). As a result, at least
one block rounding per data transfer is billed.
Starting from Firmware Version 2.31, a permanent GPRS connection is
established to the provider. Therefore, data transfers made within the billing
period (e.g., one day) are summated for block rounding. In the event of continuing
disturbances in the data transfer, the TO-PASS®telecontrol module will briefly
interrupt the permanent GPRS connection, which also effects block rounding.

3 Device Description
3.1 Scope of Delivery
The scope of delivery of the TO-PASS®telecontrol module, without options,
includes only the TO-PASS®telecontrol module. Suitable antennas are available
as accessories.
SIM Card
Please note that one SIM card is required to operate each TO-PASS®telecontrol
module and may be obtained from typical service providers such as T-Mobile,
VODAFONE or EPlus. WAGO Kontakttechnik GmbH & Co. K.G. is prepared to
assist with the selection of the most cost-effective tariff for your application.
3.2 Use
The TO-PASS®product family is designed for wireless communication of signals
and messages. This includes:
• compact module for the connection of signals from plants,
• transmission,
• preparation of values for the operator.
TO-PASS®telecontrol modules 761-217 may be used as:
• fault indicator,
• remote data request system,
• data memory,
• event logger,
• permanent on-line link,
• telecontrol modules.
The system is connected in wireless mode to PCs, hand computers, Internet PCs,
web servers, mobile telephones, fax, e-mail receivers or land-line telephones.
Influences to the system are also possible.
Communication occurs using the global mobile radio network “GSM” (Global
System for Mobile Communication). A SIM card is required for the TO-PASS®
telecontrol module to use this network. As in the case of a mobile telephone, the
TO-PASS®telecontrol module requires the SIM card in order to be able to “log
on” to the network.
When generating a new configuration file, you can select the scope of functions
based on the available firmware versions, or on the required functionalities.
Differences between these are shown in the following table.
