When the PC and NT620S/NT620C units have been connected, set the switches
at the CPU module at the PC side in order to enable communication using the NT
link method.
S C series, C200HX/HG/HE
Write the communication conditions directly to the "PC system area" (data
memory) using a peripheral tool (e.g., SYSMAC support software). For details
on the operation for setting the "PC system area", refer to the "SYSMAC
C200HX/HG/HE OPERATION MANUAL" (W303-E1-j).

With C200HX/HG/HE, the setting area differs according to which port among the
standard port of the CPU module and the ports of the expansion communication
board is used for the connection.

(*) When using C200HE, the PT unit No. range is 1 to 3.
Connect the NT620S/NT620C and host (personal computer, computer for FA
applications, etc.) using the memory link method.
In order to do this, the "memory link" system must be installed using the system
