Omron CQM1H-SCB41 Restrictions in Using the CX-Protocol, Storage Memory, Restriction Procedure

Using Protocol Macros Section 5-2

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.

computer	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.
