在此示例中,將11個(gè)遠(yuǎn)程輸入/輸出機(jī)架添加到中所述的兩個(gè)PLC網(wǎng)絡(luò)
示例1。每個(gè)遠(yuǎn)程輸入/輸出機(jī)架具有相同的19個(gè)輸入/輸出模塊;ALG222
(5) ,ALG392(6),MDL753(3),MDL655(5)。此配置在以下位置使用兩個(gè)同步程序:
100ms和300ms的周期。
By increasing the length of the logic in a sync program in PLC1 to the point where the
PLC becomes out of sync, a measurement can be made of the maximum amount of logic
solution time available for that sync program. The measurements for the example
system are shown in the following table. The measurements were taken by increasing
the logic solution time of the 20ms logic to a point just before the program becomes
synchronized. Leaving the 20ms program at that setting, another measurement was
taken in the same fashion for the 40ms sync program. This method continued through
the remaining scan sets.The table below breaks down the 20ms sync program into the different components of
the microcycle. These components are explained in Chapter 4 of the FIP Bus Controller
User’s Manual.
The breakdown measures the data as it travels from the FIP network, passes through the
FBC, and continues to the PLC application program. The breakdown continues as the
data leaves the PLC application program, passes through the FBC, and returns to the FIP
network.Example 2
In this example, 11 remote I/O racks are added to the two-PLC network described in
example 1. Each remote I/O rack has an identical assortment of 19 I/O modules; ALG222
(5), ALG392 (6), MDL753 (3), MDL655 (5). This configuration uses two sync programs at
periods of 100ms and 300ms.
