Mitsubishi Electric QJ71E71-100 User Manual page 379

*1 For the E71, the number of connections for the open process from the CPU module has increased to 16 connections.
*2 Compatible with the I/O signal and QE71(N) buffer memory
*3 Data of up to 960 words can be read from/written to an E71, and up to 480 words in a QE71(N).
*4 Availability depends on the CPU module and programming tool version.
*5 This applies to a module with the software version of Q or earlier.
*6 No EEPROM is installed. Items registered in the EEPROM of a QE71(N) are set using the parameter settings of the
programming tool.
*7 This applies to a module with the software version of E or later.
*8 This function can be used in an E71 with a serial number (first five digits) of "05051" or later. If the E71 cannot
communicate data when combined with a certain connected device, the setting can be changed in the buffer memory
(address: 1E ). (

*9 Only the QJ71E71-100 can be used.
Availability depends on the QJ71E71-100 and a programming tool version (
The response performance of the E71 to connected devices is faster than that of the A/QnA series modules. When the E71
is used, the compatibility with the A/QnA series modules cannot be precisely maintained. If there is a problem due to the
performance of the connected device, create a timing similar to that of the existing system using the CPU module constant
scan setting.
(2) Precautions for using the same program
The QnA/A series modules used for data communications between a CPU module and the connected device on
the Ethernet network can be replaced by an E71. This section describes precautions for using the same program
used in QnA/A series modules.
(a) AJ71E71(-S3) and AJ71E71N
• Program of connected devices
The following communication function programs of connected devices for an AJ71E71(-S3) and
AJ71E71N can be used for communications with an E71. However, because the response speed of the
AJ71E71(-S3) and AJ71E71N is different from that of the E71, the program may not be used as is. Before
using the same program, check the operation.
: Communications allowed by using the program for an AJ71E71(-S3) and AJ71E71N on the connected device side,
Function
Communications using a fixed buffer
("Procedure Exist")
Communications using a random
access buffer
Data read/write in the CPU module
*1 Only A-compatible 1E frame commands can be used for data communications. To perform data communications using a
command other than the A-compatible 1E frame commands, create a new program.
• Program for an AJ71E71(-S3) and AJ71E71N in the own station
Because the assignment of the buffer memory areas for an E71 is different from that for an AJ71E71(-S3)
and AJ71E71N, a program for the AJ71E71(-S3) and AJ71E71N cannot be used for an E71. Create a new
program by referring to chapters that explain each function.
• Program using an I/O signal
Programs cannot be used together with parameter settings on the programming tool.
