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 DCS5000/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.

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.
Register 3765 in an AutoMate 30 Processor and register 17565 in an

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.
