Host Link Communications

One-to-one PC Link

Up to 3 Analog I/O Units can be connected to provide analog inputs and outputs. Each Unit provides 2 analog inputs and 1 analog output, so a maximum of 6 ana- log inputs and 3 analog outputs can be achieved by connecting 3 Analog I/O Units.

The analog input range can be set to 0 to 10 VDC, 1 to 5 VDC, or 4 to 20 mA with a resolution of 1/256. (The open-circuit detection function can be used with the 1 to 5 VDC and 4 to 20 mA settings.)

The analog output range can be set to 0 to 10 VDC, –10 to 10 VDC, or 4 to 20 mA with a resolution of 1/256.

A Temperature Sensor Unit can be connected to provide up to 6 inputs for tem- perature input from sensors, such as thermocouples or platinum resistance thermometers.

The CPM1A PCs are compatible with the Host Link, which allows communica- tions with personal computers. The CPM1A using the Host Link can also com- municate with Programmable Terminal using host link commands.

An RS-232C Adapter is used for 1:1 communications and an RS-422 Adapter is used for 1:N communications.

A data link can be created with a data area in another CPM1A, CQM1, CPM1, SRM1 or C200HS or C200HX/HE/HG PC. An RS-232C Adapter is used to make the 1:1 connection.

NT Link Communications

CompoBus/S I/O Link Units

High-speed operations can be achieved by providing a direct access by con- necting the CPM1A to the OMRON Programmable Terminal through the NT Link Interface. An RS-232C Adapter is used for this connection.

Up to 3 CompoBus/S I/O Link Units can be connected to make the CPM1A a Slave Device in a CompoBus/S Network. The I/O Link Unit has 8 input bits (inter- nal) and 8 output bits (internal).

The CompoBus/S Network provides distributed CPU control based on a “PC + compact PC” configuration, which is an improvement on the earlier distributed I/O control based on a “PC + remote I/O” configuration. The distributed CPU control makes equipment modular, so designs can be standardized, special needs can be addressed, and modules can be replaced easily in the event of a breakdown.

Standard Peripheral Devices	The CPM1A uses the same Programming Consoles and SYSMAC Support
	Software (SSS) as the C200H/HS, C200HX/HE/HG, CPM1, SRM1, and CQM1
	PCs.
Programming is Possible	Programming operation is possible through the PT screen by using an OMRON
Using the PT	PT that has a built-in Programming Console function.
