11. At the scanner module screen select “input” and the display will
show the default mapped location of the 11 bytes of slave (01)
ACCESS actuator output (produced) data.
Output data from slaves is input data to the scanner. The default
mapped address of 11 bytes of input data starts at I:4.1 through
I:4.6(1st byte). Note the “4” represents the scanner slot number.
12. At the scanner module screen select “output” and the display will
show the default mapped location of the 1 byte of slave (01)
ACCESS actuator input (consumed) data.
Input data to the slaves is output data from the scanner. The
default mapped address of 1 byte of output data starts at word
O:4.1 (1st byte).
The input/output data can be remapped at these screens which is
beyond the scope of this example. It is important to note that
whenever any slaves are added or removed or remapping has been
performed, the “apply” button must be activated with the processor
in the program mode to download the changes to the scanner.
13. A flashing communication LED-D2 indicates that the slave
address connected to the network does not agree with the
network that the scanner had previously mapped or there is an
address conflict.
A slave on the network already has been assigned this address.
To correct this problem, assign and set switches 1 and 2 to an
unused address for this node and cycle the 24 VDC bus power.
Perform a new network browse and go online and upload the
network to the scanner. Select the correct slot and in the
“scanlist” delete the slave(s) that have been removed from the
network and add the new slave(s) to the network. With the PLC in
the program mode, select “Apply” and download the new data to
the scanner. When this is complete, LED-1 and LED-2 should be
on steady green.
14. In this example, with the scanner located in slot 4 the addresses
of I/O data in the SLC are as follows:
SLC INPUT TABLE: 11 BYTES OF DATA – (OUTPUT DATA
FROM THE ACTUATOR)
BYTE-1
I:4.0- (word-O-not used)
I:4.1/0- Bit 0- Actuator Closed -CW- Switch

SLC OUTPUT TABLE: 1 BYTE OF DATA – (INPUT DATA TO THE ACTUATOR)
O:4.0/0- WORD-0/Bit-0 - Establishes the operating mode of the
scanner
Bit-0 =1- Scanner maps I/O from the slaves. This Bit has to be on for
the outputs to be under SLC program control.
Bit-0 =0- Scanner stops mapping output data to the slaves. Input data
is still returned from the slaves. Outputs on the network are not under
SLC program control.
O:4.1/0 - Bits -01,2,3,4- Not Used
O:4.1/5 - Bit 5- Solenoid-1 Actuator goes CCW when =1 and
goes CW when =0.
O:4.1/6 - Bit 6- Coil-2 Not Used
O:4.1/7 - Bit 7- Resets Maintenance counter when =1 (This SLC
logic should be a momentary input i.e., a one-shot.
