“Outputs 1 byte” module:
R1 – R8 When this module is selected, the master only sends 1 byte
(coil output data S1 to S8) via PROFIBUS.
Requirement:
The “Outputs; 1 byte” module must have been selected.
Note on using the 1 byte modules
The 1 byte modules are not available in all device
combinations. If any problems occur in handling, first check
the state of the GW message in the status display of the basic
unit:
Byte Meaning Value
0 Status of R1 to R8 J Table 5 on Page 41
J The input data and control commands can now only be
used if you have selected the appropriate modules as well.
GW static: The 1-byte mode can be used
GW flashing: Check the device version of the EZ204-
DP and the basic unit. If these are valid,
check the configuration in the PROFIBUS
network and the Configurator.
