*1.The Device Unit uses a node, and so connection is possible to 63 slaves only.
*2.When the DeviceNet is used as a slave, "input" and "output" respectively refer to input from the slave to the master and output from the master to the slave.
*3.The maximum message length includes the command code when using the CMND instruction.
Caution: In the interenst of product improvement, specifications are subject to change without notice.
