Appendix 6 Register Assignments *5 The figure below shows the alarm status of the measured data and computed data. The register contains 16-bit signed integer data in the following order: alarm number 2/alarm number 1/alarm number 4/alarm number 3. Each alarm number uses 4 bits to specify a value in the range of 0 to 8.
Appendix 6 Register Assignments *8 The control data alarm statuses of registers D7614 and D7615 indicate the statuses of alarm numbers 1 to 4 of each loop using the bit status of the register (16 bits).If the status of alarm numbers 1 to 4 of each loop is ON, the corresponding bit is set to 1 regardless of the alarm type. When the data is read using ladder communications, the 16-bit signed data converted to BCD is returned. Therefore, the host computer must convert the value to 16-bit signed integer.
Appendix 6 Register Assignments *9 Registers D7801–D7803 (status of control module DI), 37004 (status of expansion module DI), D7811– D7813 (status of control module DO), D7814 (status of expansion module DIO), and D7821–D7823 (status of internal switches) show the status of each bit in the register (16-bit). The status of the DIO and internal switches are shown in order from the last bit in the register.
