1. The Serial Statistic page is used to monitor the health of the controller network These numbers will help identify when there are issues with wiring duplicate Modbus ID addresses or noise on communication wires on the controller side of the network In this example controller number 11 is experiencing failure in communication quality Timeout Errors increments anytime that a controller does not respond in an appropriate amount of time Retry Errors increments anytime that a controller does not respond after 3 attempts to read information CRC Errors increments anytime that the controller responds with a bad packet Bad Polls increments when there are timeouts and the retries did not successfully retrieve information Good Polls increments on each valid packet received Illness increments anytime that there are 5 CRC or Timeout errors in a row After a count of 5 in the Illness column the controller is flagged as having no communication On the next valid packet received the Illness value is cleared to zero and communications is restored You must refresh the browser to see these numbers update 15 I WATLOW EM Gateway Network Stats This page was loaded Wed Feb 1318 00 28 2002 IP Address Subnet Gateway Mac Address Receives Unicasts Multicasts Broadcasts Rx Errors Rx Missed Rx CRC Errors Rx Drops Transmits Buffer Defers Tx Errors Tx Collisions Tx Coll Overflow Tx FILO Errors Traffic Backoffs Network Rej2. Product Overview The EM00 GATE 0000 is a gateway bridge that allows up to 32 Watlow controllers to be directly connected to an Ethernet network Using an HTTP Browser such as Microsoft Internet Explorer or Netscape Navigator you may access 16 controllers and view several controllers parameters via an onboard Web HTTP server Ethernet Gateway The Ethernet gateway provides a means for monitoring and configuring runtime parameters of multiple controllers via a web browser The gateway is also a bridge for Modbus messages between the Ethernet bus and EIA 485 or EIA 232 links The Gateway supports full product configuration monitoring and configuration of runtime parameters via MODBUS TCP over TCP IP using a software package such as Watview sold by Watlow Ethernet Gateway Architecture This product has three physical connectivity points to the physical world They are the serial EIA 485 or EIA 232 Ethernet port 10BaseT and the power supply pins The EIA 485 EIA 232 connection supports Modbus RTU protocol and operates as a Master port It will initiate data read write requests to supported standard Watlow controllers There exists a virtual image of the controller s data points in the gateway The polling engine that initiates the Modbus RTU requests is responsible for synchronization of the virtual image and the actual controller Changes to control data occur both at the controller and at the virtual image The 10BaseT connection s
