to change the switch. When the switch is ON, resistor is active on bus. When switched the other way, the
resistor is not connected to the bus.

1/ System configuration
CANopen communication uses CANopen messages that can be set up in the “Enhanced
configuration/CANopen” menu. GENSYS 2.0 can handle a total of 13 input messages and 19 output
messages.
Three parameters must be set for each message to be used. Each message is determined by:
 The ID of the CANopen extension module (most modules use DIP switches to set their ID).
 The type of data contained in the message (analogue or digital).
 The Number of input/output channels in the message.
Note: a CANopen message can handle a maximum of 4 analogue values or 64 digital values.
The total number of CANopen inputs/outputs available is:
 44 analogue inputs.
 128 digital inputs.
 32 analogue outputs.
 64 digital outputs.
To ensure proper communication between GENSYS 2.0 and CANopen extension modules, the following
rules should be followed:
For a given CANopen module, always group the maximum number of data of the same type in one
message. For example, it is better to set up one message with 50 digital inputs than 2 messages with 25
digital inputs each.
Always group messages to/from one CANopen module. For example, do not use output messages 1 and 3
with CANopen module number 1 and message 2 with CANopen module number 2. It is preferable to use
messages 1 and 2 with module number 1 and message 3 with module number 2.
CANopen inputs and outputs can be accessed using GENSYS 2.0 variables as described below:

The lower variable number is associated to the lower message number configured. The following example
will help you understand the relationship between GENSYS 2.0 CANopen variables and physical CANopen
I/Os.
