2. Configure the I/O Block parameters as follows:
Type: Select Data Type to define a block of OCS registers, which the Produced Exchange
will periodically read and send to the EGD network. Select Status Type to define a 16-bit
OCS register, which will be written with the Produced Exchange’s Status Word.
Address: Enter an OCS Register reference (such as %R1000), for the first OCS register, in
a block of OCS registers, that will be periodically read and sent (Data Type), or for a 16-bit
OCS register that will be written with status information (Status Type).
Number of Registers: If Data Type was selected, enter the number of registers to be
periodically read and sent. If Status Type was selected, this edit box changes to Number of
Bytes, and always has a fixed value of 2.
3. Click OK to accept the Produced Exchange’s new I/O Block, which will be now be displayed
in the lower window of the Ethernet Global Data Configuration dialog (Figure 6.1).

top-to-bottom order, as they appear in the lower window of the Ethernet Global Data
Configuration dialog (Figure 6.1).
4. To add another I/O Block, click the Add Range button again and repeat steps 2 and 3. The
