  • Page 16: Timing Sequence For Communication

    4 Modbus protocol description 4.3 Timing sequence for communication Character The start and end of a data block are marked by transmission pauses. The transmission character transmission time (the time taken to transmit one character) time depends on the baud rate and the data format that is used. For a data format with 8 data bits, no parity bit and one stop bit, this is: character transmission time [msec] = 1000 * 9 bits / (baud rate) For the other data formats it is:...

    4 Modbus protocol description A minimum response time can be set in the controller, in the menu item Configuration Interface. This setting is the minimum waiting time that must elapse before an answer is transmitted (0 — 500 msec). If a smaller value is set, then the response time may be longer than the preset value (because the internal processing time is longer), the controller will then answer as soon as the internal processing is completed.

Any following characters are meaningless. Since text transmission is made as words (16-bit), if there is an odd number of characters (incl.“0”), an additional 0x00 will be added on.

    5.3 Bar code In “Bar code mode” (see Chapter 3.4 Configuration of the serial interfaces, page 12), the JUMO Logoscreen nt appears as a Slave. It waits for the ASCII string that is transmitted by the bar code reader (master).

  • Page 38: Ethernet Protocols

    6 Ethernet protocols The advantage of an Ethernet connection compared with a serial connection lies in the higher transmission rate and the company-wide accessibility. 6.1 HTTP In this case, the Logoscreen nt is configured as a slave, and handles the incoming queries as a server through port 80.

    2 bytes This protocol can be used, for instance, by the JUMO SVS 2000 visualization program (or similar programs) to read from and write to the Logoscreen nt over a company-wide Ethernet network. It is possible to access all the device variables in the Modbus address tables (see Chapter 7 Address tables, page 43).

This mail server should also have the capability of passing on e-mails to the Internet.

From the error code for the event entry (see Chapter 4.9.3 JUMO Internet error codes as integer return values, page 27), particularly error codes 120 to 173, it is possible to deduce that a parameter has been set incorrectly.
