Setting the data swap value to 1 or Reset service code is executed. If the flag is 0, the value is not saved to would result in the data being sent as 00 07 Al 20. This attribute can only be EEPROM memory in the PAX. If the flag is 1, the value is saved immediately set to O or I, all other values are ignored. The factory setting value is 0. Data to EEPROM memory in the PAX Factory setting is"on"for all Store Flags Byte is saved in EEPROM memory The attributes are grouped in blocks. Storing one attribute may cause others to be stored. If an attribute is SEt frequently, its store flag should be set to O C DIP Switch Values: (1 byte), Attribute 6, Instance 1, Class 100(decimal) to increase eeprom life Returns the dip switch setting Switch 1=LSB, I=on 3 Polling Flags:(3 bytes)Attribute 3-5, Instance l, Class 100 (decimal). The MANUAL MODE DESCRIPTION 6 DeviceNet card is continually requesting values from the pAX unit. The (CSR) Control Status Register [16](PAX) polling flags determine what values are requested during each loop. Setting The Control Status Register is used to directly control the meters outputs to“1” enables the card to poll that particula value (setpoints and analog output), or view the state of the setpoint outputs and the disables it. Turning polling flags off allows the card to request fewer values status of the temperature sensor(PAXT only). The attribute is bit mapped with and therefore decreases the internal loop time, which allows the values that each bit position within the attribute assigned to a particular control function are polled to be updated more often The control functions are invoked by writing to each bit position. The bit position definitions are TYPICAL UPDATE TIMES PAX PAXI/PAXCKPAXDP bit 0: SPI Output bit 5: Always stays 0, even if I is sent All values(10)-1.00 sec All values(19)-750 msec bit 1: SP2 Output( 0=output off bit 6: Sensor Status(PAXT only) 5 values -500 msec 10 values -430 msec bit 2: SP3 Output output on sensor norm 1 value- 100 msec 5 values -230 msec bit 3: SP4 Output I=sensor fail 1 value-52 msec bit 4: Manual mode bit 7: Always stays 0, even if I is sent If a Set Attribute is executed for any value, that value is automatically 0= automatic mode updated to the latest value, regardless of whether the polling flag is on or off. 1= manual mode On power up, all values are updated regardless of polling flag Polling flag values are saved in EEPROM memory. Factory settings In Manual Mode, the setpoint outputs are defined hy the values written to bits for all Polling flags b0, b1, b2, b3; and the analog output is defined by the value written to the AOR See Meter Attribute ldentification Chart for polling flags Internal control of these outputs is then overridden. In automatic mode, the setpoint outputs can only be reset off. Example: I Select manual mode for all outputs Value to write lu allribute 16: 0010h MANUAL MODE DESCRIPTION (CONTINUED) (MMR) Auto/ Manual Mode Register [23](PAXI/PAXCK/PAXDP) (AOR) Analog Output Register(Not PAXCK) This attribute sets the controlling mode for the outputs In Auto Mode(0)the The Analog egister controls the analog output of the meter. The meter controls the setpoint output. In Manual Mode(1) the outputs are defined manual mode must first be engaged by setting bit 4 of the CSr(PAX) or bit 0 by the attribute SOR. When transferring from auto mode to manual mode, the of the MMR(PAXI). The range of values of this attribute is 0 to 4095, which mctcr holds thc last output valuc(until the attribute is changed by a write). Each corresponds to 0 mA, 0 V and 20 mA, 10 V; rcspcctivcly. If a valuc largcr than output may be independently changed to auto or manual. Select values to place 4095 is written to the AOR Attribute, 4095 will be loaded. The table lists in manual mode by writing appropriate value to attribute 23.
