Modbus数据的编号（x）或LIL回路数据的起始信道（n）。
输入CL控制对来自网络的环路数据的更改的本地仲裁。当未配置输入CL时三个状态输出LO（在1.21固件中，此输出命名为L）、CN和CM将设置为高（1）并更改可以通过网络命令或本地面板进行。配置CL时，可以在本地进行更改从按钮开关，如PB1SW输出PS（配置为瞬时），并将从本地变为控制台或控制台/计算机到本地，输入的每个正向转换。当输出LO变高时，输出CN也将变高，CM将变低，表明控制源将变为控制台
无论何时通过输入CL上的正转换或从网络命令禁用本地。计算机可以使用网络命令将CM状态设置为高。NL输出通常连接到的MD输入按钮块PB1SW用于指示操作员面板上的C/L开关位置，C为绿色LED，红色为红色

Communications’ section. The ‘LOOP #’ and ‘LIL CHAN’ parameters enable configuration of a loop index
number (x) for Modbus data or a starting channel (n) for LIL loop data.
Input CL controls local arbitration of changes to loop data from the network. When input CL is not configured, the
three status outputs LO (in 1.21 firmware this output was named L), CN, and CM will be set high (1) and changes
can be made from a network command or the local faceplate. When CL is configured, it can be changed locally
from a pushbutton switch such as PB1SW output PS (configured as momentary) and will change from local to
console or console/computer to local with each positive transition of the input. Also, when output LO goes high,
output CN will also go high and CM will go low, indicating that the control source will change to Console
whenever Local is disabled, either by a positive transition on input CL or from a network command. The Computer
CM state can be set high using a network command. The NL output will normally be connected to the MD input of
pushbutton block PB1SW to indicate the C/L switch position on the operator faceplate, a green LED for C and a red
LED for LO.
Output WD will go high (1) when the controller fails to receive a Modbus network command within the watchdog
time. The watchdog time is set in the STATN (Station Parameters) function block. Input A can be used to
acknowledge all the alarms in all of the loops in a controller. Output PN (Pulse oN) will go high for 0.5 seconds (or
one scan cycle whichever is longer) whenever the bargraph flashes. Bargraph flashing is controlled by the priority
setting of alarms or events. Output PF (Pulse ofF) will go high for 0.5 sec when the flashing bargraph is stopped
(e.g. pressing the ACK button). ODD function blocks are one of five operator displays that
can be used on a one per loop basis to configure the local
operator display functions as well as network parameters.
See the i|ware PC faceplate example on the next page.
The ODD function block displays up to 16 discrete
variables. Each input has a corresponding block output that
is equal to the input when the variable mode is in Auto.
Each input variable can be assigned a mode. The value of
the output can be changed while in Man by using the pulser
and pressing the ACK button. When a variable is switched
to Manual it will always equal the input value until changed.
The LOOP # parameter is used to index reads and writes to
Modbus and LIL network parameters. When using the LIL,
the LIL CHAN parameter must also be configured. See
Section 6 for more information on network parameters.
The VIEW OD parameter, when set to YES enables the
operator display to be viewed and accessed locally. In cases
where it is desired to view display or operation parameters
only from a network workstation, the parameter should be
set to NO.
