    4 Modbus protocol description 4.3 Timing of the communication Character Start and end of a data block are marked by transmission pauses. The transmission character transmission time (time required to transmit one single character) time depends on the baud rate and the data format used. For a data format of 8 data bits, no parity bit and one stop bit, this is: Character transmission time [ms] = 1000 * 9 bit ÷...

    4 Modbus protocol description A minimum response time can be set in the controller under the menu point Configuration Interface. This preset time is the minimum waiting time before an answer is transmitted (0…500 ms). If a smaller value is set, then the response time may be longer than the preset value (internal processing takes longer), the controller answers as soon as internal processing is completed.

    5 Serial protocol types 5.2 Modbus master If the paperless recorder is configured as a master, (see Chapter 3.4 Configuration of the serial interfaces, Page 12), it can send Modbus inquiries in the network to slaves (e.g. other paperless recorders). The requested values are written into external instrument variables of the paperless recorder: •...

    5 Serial protocol types For each target variable, it is possible to enter the instrument address and Modbus address used to request the value. Each programmed inquiry can be deactivated by entering the instrument address 0 (if, for example, the "external analog value 2" is no longer to be written to by the Modbus master but by the Profibus).

    6 Ethernet protocols The advantage of the Ethernet connection compared with a serial connection lies in the higher transmission rate the company-wide accessibility. 6.1 HTTP In this case, the paperless recorder is configured as a slave and handles incoming requests as a server via port 80. These requests can come, for example, from a PC with setup software, PC evaluation software (PCA) or PCA communication software (PCC).

    6 Ethernet protocols 6.3 Modbus TCP In this case, the paperless recorder is configured as a slave and handles incoming requests as a server via port 502. The port can also be changed, see Chapter 3.5 Configuration of the Ethernet interface, Page 13. Modbus TCP is a standardized process, in which a Modbus telegram is packed into a TCP frame (tunnelled) and transmitted via Ethernet.
