Note!
Power supply module ECSxE
In case of the ECSxE power supply module, the PDOs CAN1_IN/OUT and
CAN3_IN/OUT cannot be used simultaneously. The PDOs to be used are
selected via C0360.
ƒ The process data objects are integrated into the ECSxA... axis modules in the form of
system blocks ( 255).
ƒ In the system blocks the user data is converted to corresponding signal types for
further use.
14.7.3.2 Structure of the process data
The process data telegrams have a maximum user data length of eight bytes each.
Process data input telegram (RPDO)
ƒ The process data input telegram transmits control information to the controller.
ƒ The control word is transmitted in byte 1 and 2 of the user data.
