Function explanation Attribute Data type Latched Remark

D6532 Axis alarm detection R/W UINT N

0: Axis alarm is not detected.

The instructions related with

the alarm axis can still be

executed when the axis

alarms.

1: When the axis alarms,

the alarm axis enters the state

of ErrorStop and the motion

instructions related with the

alarm axis stops being

executed.

2.2.3. Data exchange between MC module and PLC module

The areas for exchanging the data between MC and PLC are D6000~D6226, D6250~D6476. D6000~D6226

are where MC writes the data and PLC reads the value of the register; D6250~D6476 are where PLC writes

the data and MC reads the value of the register.

The principle is illustrated as below.

Data Exchange Figure

The program inside MC includes motion program and logic program. The data in exchange area of MC are

updated once every time all logic program execution is over. (The data in D6000~D6226 are written into

D6000~D6226 of PLC by MC and the data in D6250~D6476 of PLC are read into D6250~D6476 of MC by

MC). The data in exchange area of PLC are updated once every time one scan cycle is over. (The data in

D6250~D6476 are written into D6250~D6476 of MC by PLC and the data in D6000~D6226 of MC are read

into D6000~D6226 of PLC by PLC).
