5. Create the I/O tables with the Programming Device.
6. Set the PLC Setup serial communications port settings with the Program-
ming Device if needed.
7. Set the allocated DM area of the Analog I/O Unit with the Programming De-
vice.
The following steps are used when connected to the PLC via Host Link commu-
nications.
1. Turn OFF the PLC.
2. Set the DIP switch on the front panel of the CPU Unit. Set pin 4 to ON to use
the peripheral port and set pin 5 to OFF to use the RS-232C port.
With a CS1D Duplex System, set the DIP switch on the front panel of the
Duplex Unit. Turn ON PRPHL to use the peripheral port or turn ON COMM to
use the RS-232C port.
3. Connect the CPU Unit to the personal computer (CX-Process Tool).
4. Turn ON the PLC.
5. If FinsGateway is being used:
With the CX-Process Tool, set the network address to between 0 and 127,
the node address to 01, and the unit address to the unit number plus 10 hex-
adecimal (input in decimal) (using Network Settings from the Settings
Menu). (See section 4-2-2.)
6. If FinsGateway is being used:
Connect the CX-Process Tool via Host Link communications (using Acti-
vate Serial Port Driver from the File Menu). (See section 4-2-2.)
7. Download the function block data from the CX-Process Tool (using Trans-
fer to LC – Selected from the Execution Menu). (See section 4-3-1.)
8. Start operation from the CX-Process Tool (using Operation – Run/Stop
Command from the Execution Menu) or turn the PLC OFF and ON. (See
section 4-4.)
Note Check the following items before operating the Loop Controller.
a) Make sure the Analog I/O Units used with the Loop Control Unit/Board
are properly mounted.
b) Make sure the unit numbers on the front panel of the Analog I/O Units
coincide with the unit numbers set in the Field Terminal Function Blocks.
Data for another Special I/O Unit will be read and written if an incorrect
unit number is used.
c) Make sure the initial settings in the System Common Block in the Loop
Controller are correct. Check that the DM Area words for the Node Termi-
nal Function Block in the CPU Unit of the Loop Controller will not be used
for any other purpose.
d) When writing data to the I/O memory in the CPU Unit with function blocks
(e.g., using Send All Blocks, Expanded DO/AO Terminal to CPU Unit, or
DO/AO Terminal to CPU Unit), be sure that the words written to in the I/O
memory are not being used for any other purpose. If I/O memory words
are allocated to more than one purpose, the PLC system may act unex-
pectedly and cause injury.
9. Check the indicators on the front of the from panel of the Loop Controller: On
the Loop Control Unit, the RUN indicator should be lit and the ERC indicator
not lit. On the LCBjj, the EXEC indicator should be lit.
Note With the CS1D-CPUjjP, approximately 2 minutes is required after
power is turned ON for duplex initialization before the standby Loop
Controller will start operation. The EXEC indicator and the DPL STA-
