General Communication protocol 2 General The SIMDOS RC Plus pumps can be controlled by using the standard RS232 serial interface (COM1, COM2, … ). The RS232 serial interface allows one pump to be controlled by a PC based software tool. Any of the commands listed in this document can be carried out as single commands for pump control or verification purpose. This may be of help for customers, who want to develop their own pump control tool.

Communication protocol Initial start-up 3 Initial start-up WARNING Danger of automatic start-up The pump starts up by itself and without warning.  Do not transmit a start command until the system has been tested and is ready for operation  Mark remote-controlled pumps  Before start-up, check that hoses and equipment are leak-tight and working properly  Do not operate the pump with hazardous media 1. switch on the pump 2. Remove protective caps from RC connector plug. 3.

Universal commands Communication protocol 4 Universal commands The address number 99 has a special function. Commands, which don’t require an answer, can be sent to address 99. The command will be carried out by all pumps. This enables synchronized functions such as the start of all pumps at once. 5 Interface parameters The pump is permanently set to the following values: Name Value Baud Rate 9600 Baud Data Bits 8 Parity No Stop Bit 1 Handshake: There’s no monitoring.

Protocol answer Communication protocol 7 Protocol answer First, the pump checks the formal correctness of any received command. The Format as described in this document and LRC have to be correct. The address in the received packet has to be equal to the pump’s address. After the acceptance of the command, it will be executed. If the command has been executed, the processing of the command is either positively or negatively acknowledged.

Communication protocol Operation modes and their limitations NOTICE It is not allowed that two pumps can send their answers simultaneously The protocol answer can be deactivated (see command SPn). In this case no ACK or NACK sign is returned. The reply for commands that asked for information is always returned. 8 Operation modes and their limitations MS==0: Run Mode DT: unused DV: unused RV is forced to be within the interval [RVmin, RVmax] by the firmware.
