5-2SectionUsing Protocol Macros
65
In this manual, the protocol structure is explained in simple terms, and examples
are given of the use of the PMCR(––) instruction when controlling OMRON de-
vices using standard system protocols. For details on the protocols, the method
of modifying the standard system protocols, and the method of creating new se-
quences, refer to the CX-Protocol Operation Manual (W344).
5-1-4 Storage Memory
The protocol macros are stored in flash memory in the Serial Communications
Board and will be saved even if power to the CQM1H is turned OFF. The PC Set-
up settings for the Serial Communications Board are stored in memory in the
CPU Unit with a battery backup.
5-2 Restrictions in Using the CX-Protocol
There are some restrictions in using the CX-Protocol to manipulate protocols or
perform other operations for the CQM1H-series Serial Communications Board.
These restrictions are described below.
• Pin 8 on the DIP switch on the front of the CQM1H-series CPU Unit must be
turned ON to use the CX-Protocol. While pin 8 is ON, you will not be able to use
any of the CPU Unit or Board ports for the CX-Programmer, SYSMAC-CPT, or
SYSMAC Support Software.
• The model of PC must be set to the C200HG and the model of CPU Unit must
be set to the CPU43.
• Refer to the following table for details and for other restrictions. Unless speci-
fied, the functionality of the CX-Protocol will be the same as for the C200HX/
HG/HE.
Item Restriction Procedure
CQM1H DIP
switch settings
Turn ON pin 8 on the DIP switch on the front of the
CQM1H-series CPU Unit before attempting to use the
CX-Protocol. You will not be able to use the
CX-Protocol while pin 8 is OFF.
While pin 8 is ON, you will not be able to use any of the
CPU Unit or Board ports for the CX-Programmer,
SYSMAC-CPT, or SYSMAC Support Software. Always
turn OFF pin 8 after you are finished using the
CX-Protocol.
Turn ON pin 8 before using the
CX-Protocol.
Turn OFF pin 8 after you are finished
using the CX-Protocol.
PC model setting
(to create new
protocols)
Set the model of PC to the C200HG and the model of
CPU Unit to the CPU43-E.
1. Select New from the File Menu.
2. Select C200HG from the Change PLC
Dialog Box.
3. Select CPU43-E from the Settings
Dialog Box.
Transferring
protocols to the
computer
You will not be able to upload the data for the standard
system protocols from the Board to the computer. If an
attempt is made, the transfer will be canceled and the
following message will appear. (The standard system
protocol data in the Board will not be affected.)
Decompiler has detected an error. No protocol data
or invalid protocol list on upload. It is likely that the
previous download was interrupted or the PMSU
memory has been cleared/damaged. Try to
download a valid protocol and retry upload.
You will be able to download protocol data from the
computer to the Board (including data for the standard
system protocols) and will then be able to upload the
data. To modify the standard system protocols for your
applications, modify the data provided with the
CX-Protocol and then download the data to the Board.
