Application Precautions 5
• Be sure that the Bus Connection Unit and other items with locking devices
are properly locked into place. Improper locking may result in malfunction.
• Check the user program for proper execution before actually running it on
the Unit. Not checking the program may result in an unexpected opera-
tion.
• Confirm that no adverse effect will occur in the system before attempting
any of the following. Not doing so may result in an unexpected operation.
• Changing the operating mode of the PLC (including the setting of the
startup operating mode).
• Force-setting/force-resetting any bit in memory.
• Changing the present value of any word or any set value in memory.
• Do not install the product near devices generating strong high-frequency
noise.
• Do not drop the product or subject it to excessive vibration or shock.
• Observe the following precautions for communications cables.
• Do not lay communications cables near power lines or high-voltage
lines.
• Always lay communications cables in ducts.
• Do not pull on the communications cables or bend the communications
cables beyond their natural limit. Doing either of these may break the
cables.
• Do not place objects on top of the communications cables or other wir-
ing lines. Doing so may break the cables.
• Before touching a Unit, be sure to first touch a grounded metallic object in
order to discharge any static built-up. Not doing so may result in malfunc-
tion or damage.
• Resume operation only after transferring to the new CPU Unit the con-
tents of the DM Area, HR Area, and other data required for resuming
operation. Not doing so may result in an unexpected operation.
• Do not touch circuit boards or the components mounted to them with your
bare hands. There are sharp leads and other parts on the boards that
may cause injury if handled improperly.
• When transporting or storing Boards, wrap them in material that will pro-
tect LSIs, ICs, and other components from static electricity and be sure
that they remain within the storage temperature range.
• When creating Host Link FINS command frames using the CMND(490)
instruction, always set the unit number for Host Link incremented by one
(1 to 32) for the remote destination (send destination) node address (word
C+3, bits 08 to 15 of the CMND(490) instruction). Do not set the unit num-
ber of the actual Host Link slave (0 to 31). Using the Host Link unit num-
ber without incrementing by one will access the PLC with the entered
Host Link unit number less one.
For example, specify the remote PLC with Host Link unit number 2 by
entering
3 for the remote destination node address. If 2 is entered, the
PLC with Host Link unit number 1 will be accessed.
To access a PLC on a Host Link FINS network using the Serial Gateway
from CX-Programmer, however, enter the actual Host Link unit number,
without incrementing by one. (Select
Change PLC , click the Display
Serial Gateway Guide Button, and set unit number in the Host Link
SYSWAY Settings field of the Serial Gateway Guide Dialog Box.
