G38910120230 Carlo Gavazzi

G38910120230, Dupline® Profibus-DP Gateway Passive Type G 3891 0120, G38910120230, Dupline® Gateway with the function of a PROFIBUS-DP slave. This means that the Dupline® I/O’s (incl. multiplexed analog signals) can be read/controlled by PROFIBUS-DP masters (PLC’s, PC interface cards, etc. from various suppliers). Several Dupline® gateways can be connected to the same Dupline® network. The unit is certified by PNO (Profibus Nutzer Organisation) which ensures compatibility and interoperability with other PNO-certified products., G38910120230, The Dupline PROFIBUS-DP Gateway operates as a PROFIBUS-DP slave according to EN 50 170. This means that the 128 Dupline® I/O’s (incl. multiplexed analog signals) can be read/controlled by PROFIBUS-DP masters like PLC’s and PC interfacecards from many different suppliers. Since the G38910120 is a passive gateway without channel generator function, it is possible to connect several units to the same Dupline® network. The Dupline® PROFIBUS-DP Gateway is approved by the PNO (Profibus Nutzer Organisation) that ensures compatibility with other PNO-certified products. Configuration switches The unit is equipped with the following switches: 1 x 16-position rotary switch- not used in the G38910120. 2 x 10-position rotary switch for selection of the PROFIBUS-DP Slave Address in the range 02..99. (00..01 are reserved). Each module connected to PROFIBUS-DP must have a unique slave address which enables the PROFIBUS-DP Master to access the modules individually. 4 x DIPswitches - not used in the G38910120. 1 x DIP-switch for version selection Normally, the version selection is supposed to be in the OFF position, especially when the Gateway is used in new installations and configured with the G38_120.GSD file. In replacements or expansion of existing installations, this switch may be switched on, in order to make set the Gateway to operate towards the previous GSD version. (Mod-6590.GSD) Dupline® Input Data To ease up the Profibus Master configuration, the G38_120.gsd file is to be used. This file describes to the Master which I/O data the gateway supports. All I/O data are selectable through so-called modules, each described with its particular function. Digital Input, Digital output, Analog input etc. Through this, the individual configuration of the Gateway is quite simplified, as the user only has to select which I/O modules to use. The supported modules may be selected in any order and any combination. The G38910120 passive gateway supports one Digital input module, and one Digital output module, corresponding to the 128 channels of input and output data. Furthermore, the G38910120 automatically detects if Multiplexed analog data are present on the Dupline. Thus up to 112 Analog values may be read, and this is done through additional 14 Input modules, named "AIn (Mux:CD,0-7)", "AIn (Mux:CD,8-F)" ... "AIn (Mux:OP,8-F)". All modules consist of 16 bytes of data, and the tables below describe the content and the relations to the Dupline data. If the Dupline® signal is missing or faulty, the gateway will set the input status of all channels to OFF.
