Step 10. Connect the rail ports using a Rail I/O Interconnect Cable

(M/N 45C5), which is provided with the Rail Interface

module (1SC4000). If you are using the Ready Relay, see

section 3.5.5 for connection information.

Step 11. Turn on power to the Remote Drive Interface Head.
Step 12. Verify the installation by connecting the programming

terminal to the system and running the AutoMax

Programming Executive software.
Stop all application programs that may be running.
Use the I/O MONITOR function. Enter the slot number of

the master Remote I/O module, the Remote I/O drop

number (1Ć7), the port number (0Ć3) of the drive, and the

drive control register number (0 for the GPĆ2000). The

value displayed should reflect the status of the drive.

Remote I/O Network EmergencyĆStop

Considerations

WARNING

THE USER MUST PROVIDE AN EXTERNAL, HARDWIRED EMERGENCY STOP

CIRCUIT OUTSIDE OF THE CONTROLLER CIRCUITRY. THIS CIRCUIT MUST

DISABLE THE SYSTEM IN CASE OF IMPROPER OPERATION. UNCONTROLLED

MACHINE OPERATION MAY RESULT IF THIS PROCEDURE IS NOT FOLLOWED.

FAILURE TO OBSERVE THIS PRECAUTION COULD RESULT IN BODILY INJURY.

The Remote I/O network is designed so that network cable loss or a

slave Remote I/O or Shark Interface module failure results in outputs

on the affected racks being turned off. In the case of a master

Remote I/O module failure, all outputs on all Remote I/O network

drops will be turned off.
A hardĆwired EĆStop (Emergency Stop) circuit must be used either on

the incoming AĆC power lines to the master rack or on the master

rack and each individual slave rack which may need to be shut down

independently of the entire network.
A set of normally open contacts from the Ready Relay are provided

on the terminal strip of both the Remote I/O Head and the Remote

Drive Interface Head. The contacts open whenever a problem is

detected in the onĆboard microprocessor. Figure 3.24 shows the

composition of the relay. These contacts should be used in an EĆstop

(emergency stop) circuit to remove power from the outputs in case of

emergency. Figure 3.25 shows atypical field wiring circuit using the

contacts in an EĆstop sequence. Connections to the Ready terminals

should be made using 14 AWG wire.
