Status Areas

Master Status Area 1

An area with the exact same bit configuration as Master Status area 1 used for C200H DeviceNet Master Units, was set up. This area is called the Master Replacement Status 1.

•The following table compares the C200H DeviceNet Master Unit Master Status Area 1 and the CS/CJ- series DeviceNet Unit Master Replacement Status 1.
