2 Safety instructions
2.1 Installation and commissioning
– Never install damaged products or place them in operation. Report damages immediately to the
responsible forwarding agent.
– Installation, commissioning and service work on the device may only be performed by trained elec-
tricians with knowledge of the relevant accident prevention regulations.
– The applicable regulations and other special safety regulations for the item and application must be
observed.
2.2 User instructions
– Install and place the module in operation only if you are aware of the applicable regulations for
industrial safety and the operating instructions for the CMGA-B1 basic modules!
2.3 Intended utilization
– The module may only be used in a PROFIBUS-DP environment as a “SLAVE” sub-assembly in accord-
ance with the standard EN 50170.
– CMGA-E1-PB must not be used for safety-relevant reactions.
2.4 Operation and service
– Before installation and removal of the module or disconnecting signal and power supply cables,
power to the module must be switched off.
– During installation and removal of the module, appropriate measures must be applied to prevent
electrostatic discharge to the externally arranged terminal and plug connections.

2.5 Scope of delivery
Included in scope of delivery is:
– extension module CMGA-E1-PB
The GSD file with CMGA icon and the installation manuals can be found on the CD-ROM
GSPF-CMGA-BS... or under www.festo.com.
3 Functional description
The CMGA-E1-PB permits the user to transmit CAN telegrams (diagnostic telegram, e.g.
CMGA-B1-M2-L2-A0) through PROFIBUS DP. A maximum of 8 CAN telegrams can be received and
passed on.
The module must be parametrised as a Profibus station (slave).
The PROFIBUS baud rate of 9.6 kBaud to 12 Mbaud is recognised automatically. The size of the output
information is a maximum of 64 bytes.
The CMGA-E1-PB must be connected through a rear-wall plug connector to one or more base modules
CMGA-B1....
The Profibus plug connection must take place in accordance with the mounting regulations of the PNO.

The following settings can be made:
Setting Description
CANbaudrate Baud rate setting for CAN communication (currently, only one setting
of 500 kBit/s is permissible)
Number of CAN modules Number of CAN objects present on the card slots.
Module ID Fixed at “1”
Timeout CAN WD Timeout Timeout time for “internal” CAN communication (see configuration
of diagnostics in the programming manual)
Tab. 1 Settings for DP slave
Note:
– Only when connected to the PROFIBUS master system are the configured data accep-
ted into the CMGA-E1-PB. Otherwise, the “default settings” are valid:
Parameters Default value
CANbaudrate 500 kBit/s
Number of CAN modules 8
Module ID 1
Timeout CAN WD Timeout 8ms

5 Maintenance
5.1 Replacement of a module
Note
• Plug-in connections of the CMGA module must not be disconnected or reconnected
when powered. There is a danger of sensor damage, particularly with connected posi-
tion or speed sensors.
The following should be noted when replacing a module:
1. Remove power supply
2. Remove Profibus connecting cable
3. Take the module off the H-rail and pack it EMC-compliantly.
4. Attach the new module onto the H-rail.
5. Set Profibus address (see address of the previously installed module)
6. Plug in Profibus connecting cable
7. Activate power supply via rear-wall bus connector
