Software Setting of I/O Allocations Section 6-7
Note There are no changes in the I/O configuration information when you replace a
Dummy Unit with a SmartSlice I/O Unit. You also do not have to change the
ladder programming.
6-7-1 Starting in Software I/O Allocation Mode
On the DIP switch, turn OFF pin 1 (REGS), turn ON pin 2 (I/O), and then turn
ON or reset the Unit power supply. The CompoNet Communications Unit will
start in Software I/O Allocation Mode and you can download the Software Set-
ting Table.
Note (1) If pin 1 and pin 2 are ON when you turn ON the Unit power supply, the MS
indicator will flash in red to show an error. The operation will stop.
(2) If you turn ON pin 1 in Software I/O Allocation Mode, the TS indicator will
come ON in red for 2 seconds to show an error. The operation will contin-
ue.
(3) If you start in Software I/O Allocation Mode and there is no correct Reg-
istration Table in the CompoNet Communications Unit, there will be a
Registration Table Logic Error. The MS indicator will flash in red and I/O
operation will stop. If that occurs, make the Software Setting Table, down-
load it, and turn ON or reset the Unit power supply.
(4) The unit numbers include unit numbers for Dummy Units.
