4.2.2.3 Control Block Task Example

2400 COMMON STARTPB@ \!Start pushĆbutton

2500 LOCAL MOMENTARY@ \!Momentary output

3000 !

5000 CALL TRANSITION( INPUT=STARTPB@,

OUTPUT=MOMENTARY@)

5500 !

6000 END

The symbolic name STARTPB@ references the input module. The

symbolic name MOMENTARY@ is local to the control block task and

does not have I/O associated with it. Refer to the Control Block

Language Instruction Manual (JĆ3676) for more information.

4.2.3 Restrictions on Use in DCS 5000/AutoMax

Systems

This section describes limitations and restrictions on the use of this

module in DCS 5000/AutoMax systems.

The 24V AC/DC Input module is a read only module. Attempts to

write to it will cause a bus error (severe system error). The following

are examples from programs that write to the module and should

therefore be avoided:

a. Referencing the module from a coil in a ladder logic task.

b. Referencing the module on the left side of an equal sign in a LET

statement in a control block or BASIC task.

c. Referencing the module as an output in a control block function.

4.3 Use In AutoMate Systems

In AutoMate systems, the 24V AC/DC Input module is accessed using

the MOVMR instruction block. This block reads the data from the

module and places it into a destination register, which, depending

upon the register chosen, can then be accessed as a register or as a

in a remote rack in AutoMate systems.

AutoMate 40 Processor indicate whether there is a missing or

improperly seated module in the rack. The slots in the rack

correspond to the bits in the register, which are set to 1 (on) when a

module is missing or seated improperly. A set bit in either register

3765 or 17565 will not, however, affect the execution of the

application program.
