4 2 CSP Parameters for Modbus For the Modbus Protocol several parameters have to be set which are relevant for the communication between the control system (SCADA) and the device. he parameters and their setting possibilities or value ranges are shown in the table below. Parity (Recognition of communication errors) It is possible that the last data bit is followed by a parity bit which is used for recognition of communication errors. he paraty bit ensures that with even parity ( EVEN ) always an even number of bits with valency 1 or with odd parity ( ODD ) an odd number of 1 valency bits are transmitted. But it is also possible to transmit no parity bits (here the setting is Parity = None ). Stop Bit (End identification feature of the data byte) he end of a data byte is terminated optionally by one or two Stop-Bits. Baudrate (Data transmission rate to the host computer) he data transmission rate can be chosen from the five given values [bit/s]. Adjustment of the data transmission rate depends on the hardware of the host computer and is stated by the manufacturer of the control system. timeout (Supervision time: Reply cycle of the CSP2 to the host computer) his ime defines the maximal time in which the CSP2 can respond to a query from SCADA. If there is no reply telegram from the device sent within this time, the CSP2 discards the inquiry. In this case the host computer concludes that the CSP2 is the source for the communication failure and has to repeat the inquiry. t call (Supervision time: Inquiry cycle of the Host computer to the CSP2) Communication errors are only signalled by the CSP2 after the supervision time t call has elapsed. If the host computer does not send an inquiry telegram during this time, the CSP2 concludes that the host computer is the source for the communication failure. he signal SCADA Comm.Active is then reset. Dev.-Addr ( ) he device by which the SCADA-system (Master) identifies each of the devices (Slave) ought to be assigned only once per bus system because otherwise a clear assignment of messages within the entire system is not possible. he device can only be allocated together with the SCADA-system.

5 2.1 Notes for the SCADA-System he following times have to be considered by the control system and are to be fixed adjusted in the CSP : he dwell times (t D ) before start of a telegram must at least be set to 3.5 characters. 3.5 characters 9600 Baud = 4 ms 3.5 characters Baud = 2 ms Start of a new telegram is expected when the dwell time (t D ) is > 3.5 characters. When a break is > 1.5 characters (intermittent time), the telegram is aborted and the start of a new telegram expected. A continuous data flow is guaranteed, when the intermittent time is < 1.5 characters. At a Baudrate of 9600 Baud the intermittent time is 1.7 ms or 0.85 ms at Baud. he fact that the probability of disruptions during transmission of a telegram increases with its length has to be taken into duly consideration and thus a query to the Slave should be possibly such that the response telegram is not much longer than 32 Byte.

6 3 CSP Specific Modbus Function s For reading out data from the CSP protection device or to carry out commands, the services listed in the table, also called»function s«, are supported. Functioncode Designation Description 3 Read Holding Registers here are single or several data words read as from a specific data word. Only status es and parameter es can be read. 4 Read Input Registers here are single or several data words read as from a specific data word. Only measuring values can be read.. 6 oad Register Exactly one data word is written. 8 oopback est. est function for the communication system 16 oad Multiple Registers here are single or several data words written as from a specific data word. able 3.1: CSP function codes 6 D Modbus RU CSP GB

9 3.1 Setting Date and ime Date and time can be set by means of function code 16 and read with function code 3. When the device 0 is selected, all times of the devices connected to this bus are simultaneously reset. he devices do not respond to this command. 3.2 Supported MODBUS- Error Messages he theme Exception Response elegrams is already included in the general Modbus RU Protocol desciption. A table with code examples is shown there. For the CSP2 we want to supply more information on these. he table below contains just the actual used codes. In case the device has recognised an error it can react in the following way: Exeption Designation Description 1 Illegal Function he message received includes a function code which is not suported by the Slave. 2 Illegal Data Address Access was sought on a data word not included in the data module. 3 Illegal Data Value A value was attempted to be written which the Slave recognised to be invalid. 4 Slave Failure An unknown error has occured which cannot be specified more closely. he response given by the CSP in a failure case has the following format: Slave Address 80h + Function Exeption Checksum HI Checksum O In the second Byte of the response the Function is sent with the highest set Bit. his is equivalent to an addition by 80h. he third Byte includes the Exception of the error message.
