  • Page 27: Serial Interface Overview

    System Monitor 80175-01 SERIAL INTERFACE OVERVIEW PROTOCOLS The 3300 Serial Interface option gives the 3300 system communication capability using either RS- 232C or RS-422A connections. The interface implements two standard protocols which are switch selectable on the interface. The protocols are Modicon Modbus and Allen Bradley full duplex (DF1). Each protocol possesses its own unique characteristics but the data which is transferred over each interface link is similar.
  • Page 28 • System Monitor 80175-01 SERIAL INTERFACE OVERVIEW discussion of the message content and other related protocol details refer to the documents listed in the forward of this manual. The Serial Interface is designed to operate concurrently with either Transient Data Manager (TDM) or Dynamic Data Manager (DDM).

  • Page 29: Serial Interface Setup

    • System Monitor 80175-01 SERIAL INTERFACE SETUP Proper operation o f the Serial Interface requires that the switch and jumper settings b e set appropriate for both the configuration of the 3300 rack(s) and the style of communications between the host device and the Serial Interface. Once these settings and the proper cable connections are made, the interface can receive command messages and return response messages to a host device.

The counters will be returned in the response message in the above order. The request message will set the ADDR field to 0 and the SIZE field to 8.

  • Page 39: Data Addressing

    System Monitor 80175-01 PROTOCOL SPECIFICATIONS ALLEN BRADLEY PROTOCOL DATA ADDRESSING The Serial Interface uses fixed protocol addresses for the starting locations of rack data. These addresses are n o t the physical addresses o f the data in the interface memory. They are the addresses used in the protocol messages to access data which is available from the interface.
  • Page 40 80175-01 • S y s t e m Monitor PROTOCOL SPECIFICATIONS configuration of the rack is known, then the exact locations of all the rack's direct values can be specified. A simple formula which can be used to calculate the starting address of monitor direct values is Starting address = 8 + 2(monitor slot number - 1) + 2(number of 6-channel temperature monitors to the left of the selected monitor)
  • Page 41 System Monitor 80175-01 1 1 6 PROTOCOL SPECIFICATIONS temperature for channel 1. Channels 2 through 6 follow at addresses 19 through 23. The Allen Bradley command format will have the ADDR field set to 36 and the SIZE field set to 12.
  • Page 42 • 80175-01 System Monitor PROTOCOL SPECIFICATIONS host. The Allen Bradley command format will have the ADDR field set to 96 and the SIZE field set to 18. See note 2 at beginning of Allen Bradley Protocol Data Addressing. Example 2: Read monitor status from a 6-channel monitor in slot 7.

  • Page 43: Data Format

    System Monitor 80175-01 PROTOCOL SPECIFICATIONS ALLEN BRADLEY PROTOCOL DATA FORMAT Internally the Serial Interface converts the backplane multiplexed static data signal into a digital value using an 8-bit analog-to-digital convertor. When an analog data request message is received on Allen Bradley full duplex protocol, this 8-bit value is shifted left four bits to represent a 12-bit value.
  • Page 44 • 80175-01 System Monitor 16 I PROTOCOL SPECIFICATIONS ALLEN BRADLEY PROTOCOL EXCEPTION RESPONSES Error codes will be returned in the response message when the interface receives a message with an illegal function, address, or data range. Error codes returned in the message are Allen Bradley type REMOTE error codes.

  • Page 47 System Monitor 80175-01 PROTOCOL SPECIFICATIONS MODBUS PROTOCOL DATA ADDRESSING The Serial Interface uses fixed protocol addresses for the starting locations of rack data. These addresses are n o t the physical addresses o f the data in the interface memory. They are the addresses used in the protocol messages to access data which is available from the interface.
  • Page 48 • 80175-01 System Monitor I 1 6 I PROTOCOL SPECIFICATIONS Example 1: Retrieve the direct values from a 3300 rack which contains a vibration monitor in slot 4 and a 6-channel temperature monitor in slot 5. The vibration monitor has two values associated with it, channel one vibration and channel two vibration.
  • Page 49 • System Monitor 80175-01 PROTOCOL SPECIFICATIONS MONITOR STATUS The monitor status indicators have a value of 1 o r 0. Each monitor will have these three status values associated with it: Alert, Danger and not OK. Individual channel status is not available. If any channel of a monitor is in alert, then the monitor status is Alert.
  • Page 50 • 80175-01 System Monitor PROTOCOL SPECIFICATIONS Example 2: Read monitor status from a 6-channel temperature monitor in slot 7. The rack also has a 6-channel temperature monitor in slot 1, with slots 3, 4, 5 and 6 empty. Starting address (point number) = 3(5) = 15. Note that slot 2 is not considered an empty slot because it is occupied by the double wide 6-channel monitor.
  • Page 51 System Monitor 80175-01 PROTOCOL SPECIFICATIONS MODBUS PROTOCOL DATA FORMAT Internally the Serial Interface converts the backplane multiplexed static data signal into a digital value using an 8-bit analog-to-digital convertor. When an analog data request message is received on Modbus protocol, this 8-bit value is shifted left 4 bits to represent a 12-bit value. Since the maximum value the 8-bit convertor can have is 255, then the maximum 12-bit value is 255(16) = 4080.
  • Page 52 • 80175-01 System Monitor PROTOCOL SPECIFICATIONS MODBUS PROTOCOL EXCEPTION RESPONSES Error codes will be returned in the response message when the interface receives a message with an illegal function, address, or data range.

  • Page 54 80175-01 • System Monitor 16 I PROTOCOL SPECIFICATIONS DIAGNOSTIC REGISTER The diagnostic register is a status word that is maintained by the Serial Interface and is returned in response to a function code 8, diagnostic code 2 command. Failure of self tests will cause bits to be set in the diagnostic register.

  • Page 55: Scan Rates

    System Monitor 80175-01 PROTOCOL SPECIFICATIONS BACKPLANE DATA SCAN RATES ACTIVE MODE When there is no Communications Processor connected to the monitor rack, the Serial Interface must control scanning o f the 3300 rack backplane t o acquire direct and status values. When operating in this mode the interface data base is completely updated for an entire rack in 120 msec.

    • 80175-01 System Monitor PROTOCOL SPECIFICATIONS MODEM CONTROLS The following definitions apply to the RS-232C signals as implemented by the Serial Interface. The modem control signals DTR, DSR, DCD, RTS and CTS are active only if the MDEM switch (SW2) on the Serial Interface circuit board is set ON.

  • Page 57: Self Test

    System Monitor 80175-01 SELF TEST The Serial Interface performs the following internal self tests on power-up: Rom Check A checksum calculation is performed on the rom memory.
