INTERFACE Serial
Copper-bound transmission Interface converters RS-232 (V.24) / RS-422 (V.11) RS-232 (V.24) / RS-485 The RS-422 standard is used to create an interference-free and fast point-to-point connection between two terminals via a shielded 4-wire conductor in twisted pairs. The following tasks can be solved with the converter: —Fast and interference-free point-to-point connection between two RS-232 interfaces. —Interface conversion between RS-232 and RS-422 interfaces. —Programming and parameterizing link between PC (RS-232) and PLC or drive regulators, for example, with an RS-422 connection. PSM-ME . .. control cabinet module The interface converter PSM-ME ... realizes the bidirectional RS-232 interface conversion of the TxD/RxD data signals up to 115 .2 kbps . The device, which is only 22 .5 mm wide, is simply snapped onto standard EN mounting rails and supplied with 24 V AC or DC . The RS-232 connection is made via SUB-D9, and the RS-422/RS-485 field connection is made using pluggable COMBICON screw terminal blocks . The integrated data indicator displays transmit and receive data dynamically. High-grade 3-way isolation between supply, RS-232 and RS-422/RS-485 interface ensures reliable decoupling of the potentials with 2 kV. The integrated surge protection provides additional protection. Transient interference is discharged effectively to ground potential via the selfcontacting snap-on foot. The manifold configuration options make the device suitable for universal applications: —RS-485 2-wire mode, half-duplex —RS-485 4-wire mode, full-duplex —RS-422 4-wire point-to-point mode —Transmission rate between 4 .8 kbps and 115 .2 kbps —Automatic RS-485 transmit/receive changeover The RS-485 standard is used when more than two devices have to communicate with each other. Converting the point-to-point interface, RS-232, to the bus-capable RS-485 standard makes it possible to network up to 32 devices via a 2 or 4-wire line. The following tasks can be solved with the converter: —Coupling an RS-232 master interface to an RS-485 bus system. —Integrating an RS-232 terminal in an RS-485 bus system. —Networking of up to 32 RS-232 interfaces via the RS-485 standard (provided they can be addressed). Setting up a temporary programming and parameterizing link between PC (RS-232) and PLC or drive regulators, for example, with an RS-485 connection. This enables the converter to be used for point-to-point remote transfer with RS-422 and for networking in all common RS-485 2-wire and 4-wire bus systems. Examples of this are : MODBUS, PPI (Siemens), SUCONET-K (Moeller), DH 485 (Allen Bradley), RACKBUS (Endress & Hauser), UNI-TELWAY (Telemecanique), J-BUS (Merlin Gerin), RS BUS (Staefa), JETWAY (fetter) and many others. PSM-EG . . . control cabinet module The PSM-EG . . . control cabinet module also converts the RS-232 signals in full duplex mode with a data rate of up to 64 kbps to the powerful RS-422 standard. Additionally, the converter provides two further channels for transmitting the RTS and CTS control lines as well as the TxD/RxD transmit and receive channel. The RS-422 interface in the peripherals is galvanically isolated against both the RS-232 interface and the supply voltage with 2 .5 kV. Furthermore, the built-in surge protection barriers dissipate transient interference to the ground potential in a targeted fashion. The data cables can either be connected via SUB-D plug connectors or pluggable screw terminal blocks. The device is powered with 24 V DC (±20%) and is fitted simply by snapping it onto EN DIN rails .
