Table 57: 0x800F (32783) Language Selection

Size

Description

 

 

 

 

 

 

 

1 byte

Holds the currently selected language from the list in parameter 800E.

 

 

 

 

Table 58: 0x8010 (32784) Device Semaphore

 

 

 

 

Size

Description

 

 

 

 

 

4 bytes

The purpose of this parameter is to provide a method for tools to access a QCPort node in a non-conflicting

 

manner.

 

 

This parameter consists of a field of 2 UNITs organized as follows:

 

 

Byte

 

 

Node ID Low byte

 

 

Node ID High byte

 

 

Lockout Time in tenths of seconds Low byte

 

 

Lockout Time in tenths of seconds High byte

 

 

If the above 4 bytes are 0, anyone can write to this parameter. This parameter is cleared by the Clear Semaphore

 

command that can be sent by anyone. If all 4 bytes are not 0 and a write (other than a clear) to this parameter is

 

attempted, an error message will be returned. The parameter will be cleared when the timer counts down to 0.

 

If the node ID field is 0, all set parameters to the node will be accepted. If the node ID field is not 0, set parameter

 

commands to the node will only be accepted from the device having the same node ID as that contained in this

 

parameter. Note that if the node ID is set to zero at the same time that a non-zero value is loaded to the timer, the

 

timer will not decrement.

 

 

 

 

Table 59: 0x8023 (32803) Output Comm Loss Action

 

 

 

 

Size

Description

 

 

 

 

 

The n bytes

Used in discrete output modules. Each bit of this parameter is associated with an output bit and defines the

 

behavior of that output upon detection of communications loss.

 

 

If a bit in this parameter is 1, the output bit holds the last state.

 

 

If a bit is 0, the output bit is determined by the initial value.

 

 

 

 

Table 60: 0x8024 (32804) Input Debounce

 

 

 

 

Size

Description

 

 

 

 

 

The n bytes

Used with discrete input devices. This parameter consists of a series of UNITs, two bytes for each discrete input

 

and holds the debounce time for that input.

 

 

 

 

Table 61: 0x804D (32845) Physical Node ID Setting

 

 

 

 

Size

Description

 

 

 

 

 

 

 

2 bytes

This parameter may be used with modules having a hardware node ID switch and represents the actual setting

 

of that switch.

 

 

 

 

Table 62: 0x80CF (32975) Analog Output Communication Loss Behavior

 

Size

Description

 

 

 

 

 

 

 

n Bytes

Determines the communication loss behavior of the output module.

 

 

0

= Hold last state

 

 

1

= Use Communication Loss Value

 

 

2

= Use Initial Value

 

 

 

 

Table 63: 0x80D0 (32976) Analog Output Communication Loss Value

 

Size

Description

 

 

 

 

 

 

 

Word

Value that the output channel will go to if selected using the communication loss behavior.

 

 

1-32767

 

 

 

 

Table 64: 0x80D1 (32977) Input Range Setting

 

 

 

 

Size

Description

 

 

 

 

 

 

 

1 Word

Determines analog input data range:

 

 

0

= 0 - 10V

 

 

1

= 0 - 5V

 

 

2

= 1 - 5v

 

 

3

= 0 - 20mA

 

 

4

= 4 - 20mA

 

 

 

 

Table 65: 0x80D2 (32978) Analog Output Range

 

Size

Description

 

 

 

 

 

 

 

1 Word

Determines analog output data range.

 

 

0

= 0 - 10V

 

 

1

= 0 - 5V

 

 

2

= 1 - 5v

 

 

3

= 0 - 20mA
