2. Start-up guide

This section is intended to provide a generic guide for setting up module with a
master/controller PLC. It will cover the basic steps required to get cyclic data com-
municating using the GDNet protocol on the module.
Configuring the -GDNet module for cyclic communications
In the GDNet protocol configuration, the instances for describing cyclic data
exchange have a fixed size, which must correspond to the settings on the master
and on the device.
The network transmission speed is fixed. The module must be associated with a
unique Node Number address.
Check the Ethernet diagnostics LEDs on port A to make sure the Ethernet cable is
connected properly to the GDNet module on the drive. See the table in chapter 1.7
for a description of these LEDs.
Check that the node is set to Operational on the master device.
Decide which input/output data are to be sent cyclically (objects and/or pa-
rameters). The input/output data associated with cyclic data exchange can be
configured directly via the drive parameters (setting in the FIELDBUS M2S and
FIELDBUS S2M menus).
It is important to set a data area size that is compatible with the Master and the
GDNet device: if set on the drive, make sure the number of bytes used corre-
sponds to the size of the I/O area set on the master. The size in bytes used by
the drive is obtained from the settings in the FIELDBUS M2S and S2M menus, by
adding the size in bytes of each parameter set via the relative "Fieldbus M->S n
sys" or "Fieldbus S->M n sys" parameter, according to the table below:
The I/O data area of the "Master to Slave (M2S)" and "Slave to Master(S2M)" drive
are associated as follows:
Download the configuration to the master
After downloading the configuration to the master the LED link Data on Port A
should flash.
If configured correctly, when the master passes to "Run" mode (drive parameter
4014 "Fieldbus State" passes to "Operational") the output values sent by the master
are visible in the drive parameters associated with the channels configured in the
"Fieldbus M2S" menu, while the input values received are updated to the values of
the "Fieldbus S2M" menu parameters.
Menu Fieldbus
To enable the EXP-ETH-GD-ADV card set PAR 4000 Fieldbus type as "RTE".
The following parameters are available in the COMMUNICATION->FIELDBUS
Not assigned
Count16,Par16,Fill16,MdpPlc16,Eu
Count32,Par32,Fill32,MdpPlc32,Eu float 4 byte
M2S <-> ODB
S2M <-> IDB
The datum in question and all subsequent data
(even if assigned) do not contribute to the I/O area.
