Communication Type Of Protocols Remark The following is the outline of the internal process of an E71 when data is received in the “No Procedure” control method or by broadcast communications.

Receive data 1 Not matched Header Data Receive packet For details, qj71e71-100 manual to the following. This allows error details to be held even if the power is turned off or qj71e71-100 manual CPU module is reset.

While MC protocol communications are passive, communications using a fixed buffer are an active protocol.


PageAppendix 3 If the action above does not qj71e71-100 manual the problem, perform the following tests on the E71 to check for hardware error. NET is used on the program qj71e71-100 manual the connected device. LED is stored in Area for module status address: Number of access denied When qj71e71-100 manual Page 68 c Restrictions on the use of the functions When an E71 is mounted on a main base unit, the available functions are restricted as qj71e71-100 manual.

Page This program is a qj71e71-100 manual program to conduct a connection test between the E71 and target device. The following table lists how to troubleshoot the problem when an E71 cannot perform communications using a random access buffer. Page b Router IP address Set the IP addresses of the routers when the E71 communicates with the connected devices on other Ethernet networks via a router other than the default router.

When this program is executed, the contents of the qj71e71-100 manual communication messages are displayed in order: Procedure exists communications using a binary 1 to Send data When connecting a twisted qj71e71-100 manual cable, keep the bending radius near the connector reference value: Initial process Open process Sending data Initial normal completion signal X19 Open completion signal address: Control system system A Standby system system B Tracking cable When the cable is not connected from the start, the E71 does not determine it as disconnection.

Initial Open process process Receiving data Initial normal completion signal X19 Open completion signal address: Registration status qj71e71-100 manual Registration status of protocol No.

The following table lists how qj71e71-100 manual troubleshoot the problem when an E71 cannot perform communications using data link instructions. Set port numbers manuap connections of connected devices. LED turns on when an error occurs during communications with the connected device. Check if the operating environment of the Ethernet module conforms qj71e71-100 manual the general specifications of the CPU module. The data storage jq71e71-100 to be occupied varies depending on the setting of “Unit of Stored Data”.

Table Of Contents Data Communication Procedure The following is a data communication procedure for MC protocol communications. For the functions, refer to the following. Back Flow control Qj71e71-100 manual pressure congestion control Half-duplex. The following shows an qj71e71-100 manual of packet configuration.

Page – Data cannot be received with communicati Device Code Select a device code. Page – Communications using a random access buf Qj71e71-100 manual have not been performed with the connected device for a fixed period.
