be created.
 When DVP-ES3/EX3/SV3/SX3 Series PLC CPU acts as a Scanner and an Adapter simultaneously. It can
connected up to 8 devices (for example 4 Scanners and 4 Adapters). For Scanner, each device can establish up to
16 connections for data mapping. And for Adapter, each device can establish up to 8 connections for data
mapping. You can also use explicit message for data mapping at the same time, up to 8 explicit message
connections can be created for Scanner and Adapter respectively.
 Using device M takes 2 bytes (16 bits) as a unit in data length for IO connections, for example M0 to M15 (16 bits),
M12 to M43 (32 bits). If you need to store the data of 200 bits from M100 to M299, the data length should be set in
a value larger than 200 bits and in bytes it will be 26 bytes (26 bytes = 208 bits), the actual devices to be mapped
will be M100 to M307. D0.0 will be stored in M100 (the first bit). Pay attention on the data lengthen and the devices
to be occupied.
