Fieldbus Interface
104
Programming Information
The Fieldbus Interface card allows a PLC host to control the EVO 150 controller. The controller is
configured by parameters summarized starting on page 20. Some of these parameters may be
written by the host to change the system configuration or mode of operation and all of the
parameters may be read by the host to monitor the system status.
Fieldbus terminology
:
Fieldbus Master
The unit that controls the Fieldbus network, typically a PLC or host computer.
This controller sets the Fieldbus addresses and determines how the slaves
transmit information. There can only be one Fieldbus master per network.
Fieldbus Slave
The unit that receives commands over the Fieldbus network from the master.
This unit responds to commands when requested by the master. There may
be more than one Fieldbus slave per network.
Data Direction
Output Array: Data packet sent from Fieldbus Master (host) to Fieldbus Slave
(EVO 150).
Input Array: Data packet sent from Fieldbus Slave to Fieldbus Master.
The format of the data packets is described on the following pages.
Important:
For proper operation of the Fieldbus Interface the EVO 150 controller must be
configured for
momentary
inputs. Set parameter 27 (Power-Up Mode) to any value
except
4.
Refer to page 21 for more information about setting controller parameters.
