Communicating with a PLC-5 Adapter Channel 7-11
Configure Block-Transfer Requests
To configure block-transfers to adapter-mode controller channel, use the
adapter mode configuration screen in your programming software.
1. Define the BTW control and BTR control files you need. These control
files must already exist (appear on the memory map) or the edit will
result in an error. Each control word must contain a unique
block-transfer control address to properly transmit block-transfers.
A. Enter the block-transfer file number.
B. Enter the element number.
C. Record on paper the BT files you define. This will help when
configuring the BT files through the data monitor.
2. Since the adapter-mode channel controls the location from which data is
transferred as well as the amount of data, load data into the
block-transfer files by using data monitor screen in your programming
software.
A. Specify a BT control file you defined.
B. Enter the transfer length in .RLEN
C. Enter the file and element numbers from which the data is to be
transferred in .FILE and .ELEM respectively.
