Info

Device Setup Port Settings In this page you can make changes in the RS-232 and RS-485 configuration. This configuration is being applied to the Modbus RTU protocol when enabled in the Modbus RTU Server Protocol Settings. Match these settings to the device the gateway communicates with (Modbus Client). The possible settings are: Baudrate: 110, 300, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200 Databits: 8 Parity: None, Even, Odd Stopbits: 1, 2 Handshaking: None, RTS/CTS The factory defaults for RS-232 are: 9600, 8, N, 1, No Handshaking The factory defaults for RS-485 are: 9600, 8, N, 1. If RTS/CTS handshaking is used with RS-232, pin 7 & 8 of the DSUB-9 connector (X5) have to be connected also. NOTE: !! When applying the settings (‘Apply Settings’) all communications could be interrupted temporarily. 6/17 Persy Control Services B.V. Netherlands PBGW2.128 – P-bus Gateway PCS0113en 02.2009
P-Bus Settings (1) In this page you can make changes to the P-bus configuration. At ‘Configured Operating Mode’ you can choose the operating mode for the corresponding P-bus. The possible operating modes are: ‘Slave’ and ‘Master’. At ‘Current Operating Mode’ the current operating mode of the corresponding P- bus is being displayed. Choose Slave mode if the corresponding P-bus has already a master controller (Siemens PRU/PRV or PX) attached to it. In this mode the gateway depends on the master controller which also provides the reference voltage on the PU-line. The gateway will act as a slave on the P-bus. The green led ‘MASTER’ above the P-bus connector (X2 or X3) is off in this mode. Choose Master mode if you want the corresponding P-bus of the gateway to act as a master controller on the P-bus. The reference voltage on the PU-line will then be provided by the gateway. The green led ‘MASTER’ above the P-bus connector (X2 or X3) is on in this mode. To protect external equipment and the gateway itself, the reference voltage is switched on only when the gateway doesn’t detect any reference voltage on the PU-line. If the gateway does detect a reference voltage on the PU-line, it will configure the particular P-bus automatically in slave mode. This could lead to a P- bus configured in master mode displaying the Current Operating Mode as SLAVE. In this case, check if there is a master controller already present on the P-bus. At ‘I/O-Modules’ the number of slaves (I/O-modules) currently detected on the P- bus is being displayed. When ‘Overload’ displays YES, this means that there are too many load units detected on the P-bus. In this case, reduce the number of slaves on the P-bus. Persy Control Services B.V.
