Omron PLC address assignment -

by:Coolmay     2020-06-14
Omron PLC controller in the system unit, according to the particularity of location or unit before and after, take up the CIO area different address, understand the address allocation, input and output data of the specific location, can use programming to correct the data.

the first lecture of omron PLC address assignment

1, the CPU units assigned

X and y type XA CPU type

X and XA CPU units take 40 points in the I/O, which input 24 points, 16 output points, the CIO area input part occupies 0 ~ 1 channel, allocate a total of 24 input:

1) 12 bits to zero passage of a 00 ~ 11

(2) the other 12 bits for channel 1 00 ~ 11

3. 0 channel and 1 channel does not use a 12 ~ 15, will always be cleared, and cannot be used as internal auxiliary

X and y type XA CPU units 16 points, the output of the output section in the CIO area occupies 100 ~ 101 channels, allocate a total of 16 output:

1. Eight bits for channel 100 00 ~ 7

2. The other 8 bits for channel 101 00 ~ 7

(3) channel, and 101 of the 100 8 ~ 15, can be used as internal auxiliary a

CP1H - Type XA CPU comes with analog input and output, including four road analog input occupies 200 ~ 203 channels, two-way analog output occupies 210 ~ 211 channels.

Y type CPU

CP1H - Y type CPU with 20 points in the I/O, including 12 points, the input output at 8 O 'clock, because of the special pulse input and output terminal, input and output are assigned to discontinuous address:

1. So Y type CPU unit of input, occupy the CIO area 0 channel and a channel of a total of 12

2. 0 and 1 channel does not use a 12 ~ 15, will always be cleared, and cannot be used as internal auxiliary

Y type CPU units output of 8 points, is also due to the special pulse input and output terminal footprint:

1) the output of the CPU units take up CIO area 100 channels and 101 a total of eight

2. Do not use in the channel and 101 100 8 ~ 15, can be used as internal auxiliary a

2, extension, unit address assignment

the role of the expansion unit is expanded input, output, and expand the distribution of the unit from the CPU unit channel after the next channel, distribution address back in turn.

CP1W extension unit

take inputs such as CPU units (0 channels and 1, the output occupies 100 channels and 101, after the connection of the expansion of the CP1W unit:

(1) the input from 2 channel allocation, back in turn assigned to at most 16 channel

(2) the distribution of output since 102 channel in turn back, assigned to a maximum of 116 channel

CP1W basic I/O expansion unit, according to different input and output points, the distribution of the number of input and output channels is different also, bit allocation principle and the CPU unit of input/output bit allocation principle is the same, such as the expansion of the input and output at 8 O 'clock 12 units, input and output of each one passageway:

(1) the input bit takes up a distribution channel by 00 ~ 11, do not use a 12 ~ 15 will be cleared, and cannot be used as internal auxiliary work bit

(2) the output bit to take up a distribution channel by 00 ~ 7, do not use a 8 ~ 15 available for internal auxiliary

for analog and extension units, such as temperature sensor, its input and output channels to address, according to the number of channels for distribution, occupied CP1W - for example MAD11, distribution of the two input and one output channel.

CJ series

high function extension units CJ series high function extension unit address allocation and its unit number and unit number is on the modules of a hardware switch, special I/O unit according to the priority of the arrangement, address of 2000 ~ 2959 passageway, specific distribution is as follows:

CPU bus unit according to the priority of the arrangement, address of 1500 ~ 1899 passageway, specific distribution is as follows:

, for example,

as shown in figure 3 CP1H PLC controller configuration one Ethernet module, two basic I/O expansion unit, two analog extension unit and a temperature sensor unit, then the input and output address is how to allocate?

the correct answer is as follows:
