The communications between the NT20 and a PLC/Host are called the host
communications.
The NT20 PTs can be connected to the host using the following communica-
tions methods.
NT20-ST121-E: Host Link or NT Link (both direct connections)
NT20-ST121-E + NT20-IF001 + NT600M-LB122-V1:
C200H direct communications (direct connection)
NT20-ST128: RS-232C communications (command control)
With the NT20-ST121-E, the Host Link, 1:1 NT Link, or 1:N NT Link communi-
cations method is set using a memory switch. Other settings, such as the
band rate and automatic resetting of communications, are also set with mem-
ory switches. This section describes the communications condition settings
using the memory switches.
The NT20 has the memory areas used to store the PLC connection method,
communications conditions, system settings, etc. which can be used as the
switches and called the "memory switches". Since the memory switches use
the flash memory, the stored data can be held even when the power supply is
turned OFF.
If the memory switch memory is corrupted for any reason, a message will be
displayed when the operating mode is changed. Press the Write touch switch
and initialize the memory.
The memory switches can be set easily by using the memory switch menu in
the System Menu.
The following settings can be made with the memory switches. Refer to the
subsequent pages and 3-8 Various System Settings for details on each set-
ting and function.
