The Alog Current module is capable of providing s in the range of . Resolution of the converted sigl is 12 bits biry (1 part in 4096). The sign bit is t used in the conversion process. Both s are updated on every scan (about 5 milliseconds). User data in the %AQ registers is in a 16-bit 2’s complement fort. The 13 most significant bits from the %AQ register are converted to sign gnitude by the PLC and sent to the module. Twelve of the bits are used by the D/A converter; the 13th bit (sign) is used to determine if negative data was sent to the module. The placement of the 13 bits within the data word is shown below. The relationship between the current and the data from the D/A converter is shown in Figures 3-34 and 3-35. X D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0 X X X MSB LSB X = t applicable to this discussion.

D/A Bits vs. Current , , If the module is sent negative data, it s the low end of the current range (that is, 4 for the range). If a lue which is out of range is entered (that is. greater than 32767), the software does t accept the lue. This module provides two ranges. The default range is with user data scaled so that a count of 0 corresponds to 4 and a count of 32000 corresponds to 20 with each 1000 counts representing 0.5 . When a RANGE jumper (either RANGE1 or RANGE2) is added to the I/O termil board, the range is with user data scaled so that a count of 0 corresponds to 0 and a count of 32000 corresponds to 20 with each 800 counts representing 0.5 . The range of each can be programmed individually. The module provides a full 12 bits of resolution in either range. Scaling of the is as shown in Figures 3-36 and 3-37.

Scaling for Current Figure 11-8. Scaling for Current , , The state of the module if the goes to the STOP mode or RESET, can be either Default to 0/4 or Hold-Last-State. Selection of the desired state is de by configuring the DEF0/4 jumper on the detachable termil board connector on the module. If the jumper is t installed, the s will Hold-Last-State on STOP or RESET provided that a backup user supply is connected when the system power goes down. If the DEF0/4 jumper is present, the module defaults to 4 on the range or 0 on the range on STOP or RESET. One jumper per module is used to program both s for Hold-Last-State or DEF0/4. Each module y be used as a current source or as a less accurate voltage source.
