1. 4 July 16 1998 Important Product Information Factory LAN TCP IP Ethernet Interface GFK 1085K interface can then be reached by the IC641 TCP IP Ethernet programming software Refer to TCP IP Ethernet Communications Station Manager Manual GFK 1186 for details Note This method of assigning an IP address is not recommended when the PLC CPU firmware is older than version 6 50 because an unconfigured Ethernet Interface is unable to operate for two minutes after the PLC is powered on Proper IP Addressing is Always Essential The Ethernet Interface must be configured with the correct IP Address for proper operation ina TCP IP Ethernet network Use of incorrect IP addressing can disrupt network operation Refer to TCP IP Ethernet Communications User s Manual GFK 1084 for important information on IP addressing AAUI Cable Attachment Power to the PLC must be turned off whenever the transceiver cable AAUI cable is connected or disconnected at the Interface or at the transceiver Sudden changes in power supply loading caused by connecting or disconnecting the transceiver with power on may result in unexpected operation of the Ethernet Interface PLC CPU or other modules Connecting the transceiver with power on may also blow the protective fuse A blown fuse cannot be replaced in the field the Ethernet Interface must be returned for repair SQE Enable The Ethernet Interface requires that the SQE test signal be enabled on the t2. The new killss station manager command has been added in this release of the IC693CMM321 TCP IP firmware The killss command can be used to manually terminate established SRTP Server endpoints This command is intended for maintenance and diagnostic purposes only The syntax for the command is as follows killss all lt SRTP Server endpoint gt lt SRTP Server endpoint gt killss all causes all established SRTP Server endpoints to be terminated If the endpoint numbers as shown in the output of stat v command are specified only those endpoints would be terminated This command will not terminate any endpoints which are not in ESTABLISHED state The killss command is a modify command therefore the user is required to be logged in before using this command Enhanced Station Manager Output for statv To help in debugging a PLC setup the number of received requests and the IP address of the client for every SRTP Server endpoint have been added to the display in response to stat v station manager command Issues Resolved by Firmware Release 2 10 ID Code Description 54641 Under heavy load conditions it is possible for the CPU to reject requests made through the Ethernet Interface with an error code signaling that the CPU has a full queue When this occurs the Ethernet Interface will now retry this request a maxi mum of 5 times before forwarding this error to the requester 8
