Pre-Ver. 1.2 Units
Programming or monitoring of a serially connected PLC from the CX-Pro-
grammer during execution of a protocol macro (e.g., Host Link Master Proto-
col) requires the CX-Programmer to be directly connected to the serially
connected PLC. This configuration is not possible, however, if the serially con-
nected PLC is on a moving body connected through a serial wireless modem.

Unit Ver. 1.2 or Later
The Serial Gateway can also be used in protocol macro mode. When protocol
macros are used for serial communications, the Serial Gateway is prohibited
by turning ON the Serial Gateway Prohibit Switch in the CIO Area and
enabled by turning OFF this switch. This option enables, for example, pro-
gramming or monitoring of a serially connected PLC from a CX-Programmer
that is connected to the PLC during execution of protocol macros (e.g., Host
Link Master). This function also enables continuous programming/monitoring
from the CX-Programmer when the serially connected PLC is on a moving
body connected through a serial wireless modem, making it particularly effec-
tive.
CX-Programmer
The remote PLC is on a moving body. Therefore, direct serial connection for
programming/monitoring the PLC is not possible. Access is possible, however,
by using the Serial Gateway during execution of the protocol macro.
