CPM2C-S Features and Functions
Section 1-1
Complete Communications Capabilities
Host Link
A Host Link connection can be made through the PC’s communications port
used as a RS-232C or peripheral port. A personal computer or Programmable
Terminal connected in Host Link mode can be used for operations such as
reading/writing data in the PC’s I/O memory or reading/changing the PC’s
operating mode.
No-protocol
Communications
The TXD(48) and RXD(47) instructions can be used in no-protocol mode to
exchange data with standard serial devices. For example, data can be
received from a bar code reader or transmitted to a serial printer. The serial
devices can be connected to the communications port as a RS-232C or
peripheral port.
High-speed 1:1 NT Link
Communications
In a 1:1 NT Link, an OMRON Programmable Terminal (PT) can be connected
directly to the CPM2C-S. The PT must be connected to the communications
port as an RS-232C port (not as a peripheral port).
1:1 Host Link Communications
1:N Host Link Communications
(Up to 32 PCs can be connected.)
