processing the response this function block will perform the word swap-
ping automatically. Refer to Appendix B Function Block Programming for
more details.
Writing the lower limit of the setpoint to the upper limit of the setpoint for chan-
nel 1 is done with the command: 0102C1000300000100000005(hex).
The response is (no error occurred): 01020000(hex).
A write or operation command will be sent to the Temperature Controller
when the command is changed from zero's to the correct data. When the
command data is set to zero, the response data will also be cleared. The read
type command blocks are sent every Compoway-F cycle.
Broadcasting can be used for operations and writes. If the device address is
set to 00FF(hex), a broadcast is sent to all TC's using XX broadcast. The
response code will be filled with a response to indicate that the command has
been sent to the TC's.
Note It is recommended that free communication blocks are restricted to the end of
the configuration. Placing a free communication block in the middle of other
modules is allowed, it will influence the device number of other modules. The
device number is affected due to the fact that the slot number is a representa-
tion of the device number.
Configuring 2 x E5ZN basic modules and a free communication write block:
If there is no device for a device address between two existing consecutive
device addresses, the empty slot module must be used. The slot number rep-
resents the device address.

Note The PROFIBUS Configuration for this slave is limited to 200 bytes input and
200 bytes output.
The Gateway has an implemented RS-232C interface. With this interface it is
possible to connect to an IBM compatible computer with a serial port and
send and receive data to a TC using the software package CX-Thermo. The
RS-232C auxiliary interface can only communicate with Compoway-F bus.
Before using CX-Thermo DIP-switch 4 must be set on, a group of four DIP-
switches is located on the front of the Gateway Unit.
Note CX-Thermo is not shipped with the Gateway Unit.
