When enabled by the Transmit Global Data Enabling Registers

(registers 50Ć53), the individual points within these registers are

broadcast to all other drops on the network. A global coil is enabled

by setting its corresponding bit in the Transmit Global Data Enabling

Registers.

WARNING

IT IS THE USER'S RESPONSIBILITY TO ENSURE THAT ANY GIVEN GLOBAL BIT

IS ENABLED TO BE TRANSMITTED IN ONLY ONE DROP. FAILURE TO DO SO

WILL CAUSE RANDOM BEHAVIOR OF THE GLOBAL DATA. UNEXPECTED

MACHINE MOVEMENT COULD RESULT. FAILURE TO OBSERVE THIS

PRECAUTION COULD RESULT IN BODILY INJURY AND/OR DAMAGE TO THE

EQUIPMENT.

Example:
Transmit Global Data Enabling Register 50
17 16 15 14 13 12 11 10 07 06 05 04 03 02 01 00(octal)
15 14 13 12 11 10 09 08 07 06 05 04 03 02 01 00(decimal)

0 0 0 0 1 0 0 0 1 0 0 0 0 0 0 0

Global Data Register 121 (AutoMate Image Register 71)
17 16 15 14 13 12 11 10 07 06 05 04 03 02 01 00(octal)
15 14 13 12 11 10 09 08 07 06 05 04 03 02 01 00(decimal)

1 1 0 0 1 1 0 0 0 1 0 0 0 0 0 0

In the above example, bits .13 and .07 (octal) have been set in

Transmit Global Data Enabling Register 50. Therefore, the status of

bits .13 and .07 (octal) of the corresponding Global Data Receiving

Register, register 121 (AutoMate image register 71), is now global

and will remain global until a zero is written to bits .13 and .07 in

register 50. When not enabled by the Transmit Global Data Enabling

Registers, bits in registers 71.00 Ć 74.17 are used as global inputs.
In figure 4.5, when global coil 1771.00 is executed in the A40 Node 0,

its status is passed to the RĆNet processor. When Node 0 gets the

token (access to network), the status of all global coils from Node 0

are sent over the network. The information is received by all the RĆNet

processors as well as the AutoMax RĆNet Processor. When the

AutoMate 30 and the AutoMax (Nodes 1 and 2) do their next scan,

contact 71.00 (A30) and 71.00 (AutoMax) will assume the new status

as determined by global coil 1771.00. When Node 0 is finished, the

token is passed to Node 1. From Node 1, it is passed to Node 2 and

then back to Node 0.
