Sorensen DCS, DLM, PRO-T Series Configuration 2.4 Remote Programming Via RS-232 The M9s RS-232 interface operates at 19.2Kbaud with 8 data bits, no parity, and 1 stop bit. All M9 commands are supported at the

21、RS-232 interface with the exception of the Service Request (SRQ) function which is a GPIB-specific function requiring the dedicated Service Request line of the IEEE-488.2 interface. In this case, the SRQ function has no effect. The RS-232 interface is accessible through the rear panel 6-pin RJ-11 co

22、nnector; on DLM Series 600W, the connector is labeled RS232(485).

23、 with the M85 Option The M85 option is an auxiliary controller used in conjunction with the M9 to provide multiple sources controlled by a single GPIB address or via a single RS-232 connection. Up to 30 power supplies can be attached to a single M9 via the EIB(RS-485) bus connection at the rear pane

24、l of the M9. The EIB(RS-485) is accessible through the rear panel 6-pin RJ-11 connector.

25、be the operation of the M9 by remote programming using the M9 IEEE-488.2 and SCPI command sets. The M9 IEEE488.2 and SCPI command sets provide programming, query, and status commands that facilitate remote control of the power supply. IEEE-488.2 Register Definitions The M9 supports the IEEE-488.2 an

26、d SCPI 1995.0 status reporting data structures. These structures are comprised of status registers and status register enable mask pairs. The following sections describe these pairs. SCPI Status Byte The SCPI Status Byte status register can be read by the *STB? command or by issuing a GPIB serial po

27、ll. The Status Byte status register can be cleared by the use of the *CLS command. The M9 can be configured to request service from the GPIB controller by setting the appropriate bits in the Service Request Enable Register (SRE). The SRE register has the same bit pattern as the Status Byte. It is mo

28、dified using the *SRE command and read with the *SRE? command. For example, if the SRE register is set to 0 x10 (MAV), when the M9 unit has a message available, the Status Byte register will contain 0 x50 (RQS and MAV) and the SRQ line of the GPIB will be asserted to indicate a request for service.

29、See table below, and refer to Section 7 for further information. M9 Programming Manual 3-1 IEEE 488.2 and SCPI Command Operation Sorensen DCS, DLM, PRO-T Series SCPI STATUS BYTE Bit Hex Value Description 0 0 x01 Not used. 1 0 x02 Protection Event Status flag. Indicates the selected protection event

30、occurred. 2 0 x04 Error/event queue message available. Set when any error/event is entered in the System Error Queue. It is read using the SYSTem:ERRor? query. 3 0 x08 Questionable Status flag. Indicates the quality of the current data being acquired. This bit is not used. 4 0 x10 Message available

31、(MAV). Indicates a message is available in the GPIB output queue. Cleared after the GPIB output buffer is read. 5 0 x20 Standard Event Status Register (ESR). Summary bit for the ESR. Set when any of the ESR bits are set and cleared when the ESR is read. 6 0 x40 Request Service flag (RQS) for serial

32、polling or Master Summary Status (MSS) in response to *STB? If service requests are enabled (with the *SRE command), this bit represents the RQS and will be sent in response to a serial poll, then cleared. If RQS is not enabled, the bit represents the MSS bit and indicates the device has at least on

33、e reason to request service. Even though the device sends the MSS bit in response to a status query (*STB?), it is not sent in response to a serial poll. It is not considered part of the IEEE-488.1 Status Byte. 7 0 x80 Operation Status flag. Indicates the current operational state of the unit. This

34、bit is not used. 3.2.2 Standard Event Status Register (ESR) The Standard Event Status Register (ESR) can be read by the *ESR? command. Reading this register or issuing a *CLS command will clear the ESR. Use the *ESE (Standard Event Status Enable Register) to enable corresponding ESR bits to be summarized in the summary bit of the SCPI Status byte. To configure the M9 to generate GPIB service requests based on the ESR, both the Standard Event Status Enable Register and the Service Request Enable Register must be programmed. See table below, and
