WAGO-I/O-SYSTEM 750 CAN Technology 15
750-658 CAN Gateway
Manual
Version 1.2.1, valid from FW/HW-Version 01/01
3 CAN Technology
The CAN bus is an asynchronous serial bus system for connecting intelligent
actuators and sensors to the control level. CAN standards for "Controller Area
network" and defines a communication standard developed in the mid-1980s for
data transmission in automobiles.
The so-called "Data Link Layer" is defined in the CAN specification. This is the
physical layer and data link layer. The message format is described in detail.
In addition, the so-called "CAN Application Layer" (CAL) is defined in the CAN
specification. CAL is a general description language for CAN networks and
makes a number of communication services available.
Network management powers up the network in a simplified manner. This
network can be extended by the user as required.
CAN is a so-called "Multi-Master Bus System". Contrary to other fieldbus
systems, the I/O modules connected to the bus are not addressed, but the
messages are identified. The devices are allowed to send messages whenever
the bus is available. Bus conflicts are solved by assigning messages a specific
priority. This priority is defined by the so-called "CAN-ID" (CAN identifier). It is
uniquely assigned to a communication object. The smaller the identifier, the
higher the priority. Thus, communication without bus master module is thus also
possible.
There are two CAN standards:
• "2.0A Standard Frame"
• "2.0B Extended Frame"
The "2.0A Standard Frame" makes it possible to address up to 211 different CAN
identifiers. The "2.0B Extended Frame" was later developed to support up to 229
different CAN identifiers.
Each bus node decides by itself when it wants to send data. However, it is also
possible to request other bus nodes to send data. This request happens via the
so-called "Remote Frame".
Based on CAN, various protocols have been established on the market at higher
layers. These may include CANopen, DeviceNet and SAE J1939. Support for
these protocols is left to future module variants.
Additional information about the CAN bus!
Additional information about the CAN bus is available on the Internet at
www.can-cia.org.

4.2.2 Power Jumper Contacts/Field Supply
Risk of injury due to sharp-edged blade contacts!
The blade contacts are sharp-edged. Handle the I/O module carefully to prevent
injury. Do not touch the blade contacts.
The I/O module 750-658 has 2 self-cleaning power jumper contacts that supply
and transmit power for the field side. The contacts on the left side of the I/O
module are designed as blade contacts and those on the right side as spring
contacts.

Do not exceed maximum values via power contacts!
The maximum current that can flow through the power jumper contacts is 10 A.
The power jumper contacts can be damaged and the permissible operating
temperature can be exceeded by higher current values.
When configuring the system, do not exceed the permissible maximum current
value. If there is a higher power requirement, you must use an additional supply
module to provide the field voltage.
