wide operation, with byte-wide being the default. In addition, on
firmware revisions 18.1 and beyond, there is a byte-wide fast
output mode available that reduces the output string size,
significantly cutting down on the data transfer time from the 1260
Option 01 to the Slot 0 controller. Data is formatted in either
decimal, hexadecimal or binary, with the default being decimal.
The width and format of the output are specified as follows:
Example 1:
Assume that ports 5-11 are defined as asynchronous and are tri-
stated, port 5 is sensing a 23, port 6 is sensing a 0, port 7 is
sensing 127 and the user sends the following command:
READ 1.5-7,Y
The user would read back:
001. 1260-14C DIGITAL INPUT/OUTPUT MODULE<CR>
<LF>
001. 05: 23<CR><LF>
001. 06: 0<CR><LF>
001. 07: 127<CR><LF>
001.END<CR><LF>
Example 2:
Assume that all ports are defined as asynchronous and are tri-
stated, port 0 is sensing a hex 1e, port 1 is sensing a hex c7, port
2 is sensing a hex d3, port 3 is sensing a hex a0 and the user
sends the following command:
READ 1.0-2,W,H
The user would read back:
001. 1260-14C DIGITAL INPUT/OUTPUT MODULE<CR>
<LF>
001. 00: C71E<CR><LF>
001. 02: A0D3<CR><LF>
001.END<CR><LF>
An "X" causes a bit-wide read of the port. Any combination of the
8 bits from X0-X7 may be read simultaneously. The output will
contain the status of each bit in binary format and in the same
order as specified in the command.
