Using device D or device M takes 2 bytes (16 bits) as a unit in data length for I/O connections, for example M0 to M15 (16 bits), or M12 to M43 (32
bits). If you must store the data of 200 bits from M100, the data length must be set in a value larger than 200 bits, and in bytes it is 26 bytes (26 bytes
= 208 bits). The actual devices to be mapped are M100 to M307. D0.0 is stored in M100 (the first bit).
Array-typed tags are NOT supported in explicit messages.

Maximum number of connections when using the PLC to connect to other devices through Ethernet/IP™:
•
The PLC can act as a Scanner and an Adapter simultaneously. It can be connected up to 16 devices (for example 8 Scanners and
8 Adapters).
•
When the PLC acts as a Scanner, it can connect to up to 16 devices. Each device can establish up to 32 connections for data
exchange. Data exchange types can be I/O connection and Consumed Tag. You can use explicit message for data exchange at
the same time, up to 16 explicit message connections can be created.
•
When the PLC acts as an Adapter, it can connect to up to 16 devices. Each device can establish up to 8 connections for data
exchange. Data exchange types can be I/O connection and Produced Tag. You can use explicit message for data exchange at
the same time, up to 8 explicit message connections can be created.
