  • Page 3: Introduction

    GK473 gateway (interface converter) is a connecting device enabling communication between the spindle position displays (SPAs) of the Baumer IVO Multicon system (for example N 140 / N 142 / N 150) and a DeviceNet-capable PLC. The gateway converts the SPA data blocks from RS485 interface into the DeviceNet protocol (and vice-versa).

    The data content is according to I/O Poll. GK473 will only produce and transfer data to the DeviceNet master upon any change of state at the RS485 sub bus. Utilizing the Change-of-State messages means a considerable reduction of data volume in the DeviceNet bus.

    DeviceNet read-in. The AutoScan function relieves the CANopen master from proceeding cyclic SPA scanning operations itself. This operating mode is necessary to make the batched information objects (GK473 class Attribute 3..7) provide valid data. However, there might be situations where this is not desired Several commands to the SPA are only valid for the time being until another command is received (for example indicate SPA ID in the lower display line).

    Any timeout administered by the DeviceNet Master for monitoring of gateway reply should not be less than 400 ms. The DeviceNet Master transmits to GK473 the transmission data within the limits SOH and EOT out of the complete command to the addressed spindle position display (SPA). Length is always 16 bytes since digits not utilized are filled up with 0.
