•
Data links provide automatic transfer of up to 2,966 words of data in the LR
and/or DM Areas.
•
Data transfers of up to 256 words each can be implemented by programming
the NETWORK READ (RECV(98)) and NETWORK WRITE (SEND(90))
instructions in the user program.
•
Data transfers via datagrams are also available using a command/response
format.
•
A C200HW-COM01 or C200HW-COM04-E Communications Board and a
C200HW-CE001 or C200HW-CE002 Bus Connection Unit are required to use
a SYSMAC LINK Unit.
The C200H-APS03 Auxiliary Power Supply Unit is used as a backup power sup-
ply for optical SYSMAC LINK Systems.
