Function Description WAGO-I/O-SYSTEM 750 750-652 Serial Interface RS-232 / RS-485 5 Function Description 5.1 Operating Modes for Serial Transmission In den In the operating modes for serial transmission, the I/O module allows communication with serial devices via RS-232, RS-485, RS-422 or DMX. The I/O module operates in these modes as a link between one of these standardized interfaces to the one side and the application or controller to the other side.
WAGO-I/O-SYSTEM 750 750-652 Serial Interface RS-232 / RS-485 5.1.1.1 Function Description 35 Continuous Transmission The I/O module can be set either to transmit data in the output buffer to the serial interface immediately or to start the transmission process only after released by the application.
Function Description WAGO-I/O-SYSTEM 750 750-652 Serial Interface RS-232 / RS-485 The time period after which the I/O module starts data transmission can be defined using the "Continuous Receive Timeout" parameter. Because the duration of the transfer of any amount of data depends on the baud rate setting, number of data and stop bits and the parity, an absolute time specification is not feasible.
WAGO-I/O-SYSTEM 750 750-652 Serial Interface RS-232 / RS-485 5.1.3.3 Function Description 37 Flow Control Using RTS/CTS, RTS with Lead/Follow-on Time With firmware version 03 or higher, the I/O module allows RTS/CTS for communication with serial devices that only support a half-duplex connection. This is important, for example, for communication with some telecontrol modems. If this type of flow control is activated, the I/O module sets RTS while it transmits data to the serial interface.
Function Description 5.1.6 WAGO-I/O-SYSTEM 750 750-652 Serial Interface RS-232 / RS-485 DMX Operating Mode The DMX operating mode is also available with firmware version 03 or higher. In this mode, the I/O module functions as a DMX sender and allows up to 31 nodes to be connected. The transmission channel is based on RS-485 physics with a transmission rate of 250 kBaud, as well as 1 start and 2 stop bits. In this mode, no further settings are possible.
WAGO-I/O-SYSTEM 750 750-652 Serial Interface RS-232 / RS-485 Function Description 39 Figure 7: Internal Structure If two I/O modules are connected together in this mode, each I/O module transmits the data bytes of the process output image cyclically to the I/O module on the opposite side. Received data bytes of the process output image on the opposite side are again represented as data bytes in the process image of the local I/O module. The sequence of data bytes remains unchanged during transmission.
