high level (corresponds to 100% of the digital inputs).
If the maximum voltage at the inputs is 30 V, only 12 digital inputs of 16 digital inputs of one
group may be simultaneously at high level (corresponds to 75% of the digital inputs).
General technical specifications
For information on the general technical specifications, such as standards and approvals,
electromagnetic compatibility, protection class, etc., refer to the , ET 200MP system This appendix contains the dimension drawings of the compact CPU installed on a mounting
rail. You must take the dimensions into consideration for installation in cabinets, control
rooms, etcYou have the option of reassigning parameters for the analog on-board I/O in RUN (for
example, measuring ranges of individual channels can be modified in RUN without affecting
the other channels).
Changing parameters in RUN
The parameters are transferred to the analog on-board I/O via data records with the WRREC
instruction. The parameters set with STEP 7 (TIA Portal) are not changed in the CPU, which
means that the parameters set in STEP 7 (TIA Portal) will be valid again after a restart.
The parameters are checked for plausibility by the analog on-board I/O only after the
transfer.
Output parameter STATUS
If errors occur when transferring parameters with the "WRREC" instruction, the analog onboard
I/O continues operation with the previous parameter assignment. However, a
corresponding error code is written to the STATUS output parameter.
You will find a descrtion of the "WRREC" instruction and the error codes in the STEP 7
(TIA Portal) online help.If errors occur when transferring parameters with the "WRREC" instruction, the analog onboard
I/O continues operation with the previous parameter assignment. However, a
corresponding error code is written to the STATUS output parameter.
You will find a descrtion of the "WRREC" instruction and the error codes in the STEP 7
(TIA Portal) online helpThe parameters for the 5 analog input channels are located in data records 0 to 4 and are
assigned as follows:
● Data record 0 for channel 0
● Data record 1 for channel 1
● Data record 2 for channel 2
● Data record 3 for channel 3
● Data record 4 for channel 4The following table contains all measuring ranges of the inputs of the analog on-board I/O
with the corresponding codes. You must enter these codes in each case in byte 3 of the data
record for the corresponding channel (refer to the figure Structure of data record 0: Bytes 0
to 6).
Table B- 2 Codes for The following table lists all temperature coefficients for temperature measurement of the
thermal resistors along with their codes. You must enter these codes in each case in byte 4
of the data record for the corresponding channel (refer to the figure Structure of data record
0: Bytes 0 to 6)The values that can be set for hardware interrupts (high/low limit) must be within the nominal
range and overrange/underrange of the relevant measuring range.
The following tables list the permitted hardware interrupt limits. The limits depend on the
selected measurement type and measuring range. The values that can be set for hardware interrupts (high/low limit) must be within the nominal
range and overrange/underrange of the relevant measuring range.
The following tables list the permitted hardware interrupt limits. The limits depend on the
selected measurement type and measuring rangeThe parameters for the 2 analog output channels are located in data records 64 and 65 and
are assigned as follows:
● Data record 64 for channel 0
● Data record 65 for channel 1
Data record structure
The figure below shows the structure of data record 64 for channel 0 as an example. The
structure is identical for channel 1. The values in byte 0 and byte 1 are fixed and must not be
changed.
You enable a parameter by setting the corresponding bit to "1"The following table contains all output types of the outputs of the analog on-board I/O with
the corresponding codes. You must enter these codes in each case in byte 2 of the data
record for the corresponding channel (see the previous figure).The following table contains all output ranges for voltage and current of the outputs of the
analog on-board I/O with the corresponding codes. You must enter these codes in each case
in byte 3 of the corresponding data record (see previous figure).The following table lists all output ranges for the permitted substitute values. You must enter
these substitute values in each case in bytes 6 and 7 of the data record for the
corresponding channel (see the previous figure). You can find the binary representation of
the output ranges in the section Representation of output ranges (Page 183).You have the option of reassigning parameters for the digital on-board I/O in RUN (for
example, values for input delay of individual channels can be modified in RUN without
affecting the other channels).The parameters are transferred to the digital on-board I/O via data records 0 to 15 with the
WRREC instruction. The parameters set with STEP 7 (TIA Portal) are not changed in the
CPU, which means the parameters set in STEP 7 (TIA Portal) will be valid again after a
restart.
The parameters are only checked for plausibility after the transfer.
