J HOST LINK
A Host Link connection can be made through the CPM2A’s RS-232C port or Peripheral port. A personal computer or Programmable Ter-
minal connected in Host Link mode can be used for operations such as reading/writing data in the CPM2A’s I/O memory or reading/chan-
ging the controller’s operating mode.
No-Protocol Communications
The transmit TXD (48) and receive RXD (47) instructions can be used in No-Protocol mode to exchange data with standard serial de-
vices. For example, data can be received from a bar code reader or transmitted to a serial modem. The serial devices can be connected
directly to the RS-232C port or the Peripheral port using the CPM1-CIF01 serial communications adapter.
J 1:1 DATA LINKS
A CPM2A can be linked directly to another CPM2A, CQM1H, CPM1, CPM1A, CPM2C, SRM1(-V2), or a C200HS or C200HX/HG/HE
programmable controller. The 1:1 PLC Link allows automatic data link connections or sharing of memory between two Omron CPUs. The
controller must be connected through the RS-232C port; it cannot be connected through the Peripheral port.
