*1. Refer to the DeviceNet Operation Manual (W267) for the communications power supply specifications.
*2. The Master Unit uses one node. Therefore 63 Slave Units can be connected.
*3. C200HS Series are not connected.
*4. A maximum of 80 words per block can be used if the Master Unit is mounted to the C200HS Series.

Limitations on Master Unit Installation

With CS1H/G PLCs, make sure that the output area allocated to slaves and the area used for actual I/O (e.g., for Basic I/O Units) do not overlap.
The Master Units for the CS1H/G, C200HX, C200HG, C200HE, and C200HS overlap with the SYSMAC BUS Master Unit in allocated area. Therefore, it will not possible to mount the DeviceNet Master Unit and SYSMAC BUS Master Unit together to the same PLC unless the Configurator is used.
The Configurator cannot, however, be used with the C200H Series.

General Specifications

The specifications of the Unit are the same as those of the CS1H/G, C200HX, C200HG, C200HE, and C200HS. For specifications of CS1-series and C200HX/HG/HE PCs, refer to the respective catalogs (CS1 Series: P047; C200HX/HG/HE: P036).
