7.8 Hitachi Industrial Equipment System
With Hitachi HIDIC-H Ethernet Protocol units, when the same
project file is used on multiple GP/GLC units, the system may malfunction. When using multiple GP/GLC units, create and maintain only one unique project file for each GP/GLC unit.

*3 When using optional Ethernet I/F unit, a bus conversion unit (PSL-CONV00)
is required.
* 4 Using the optional Ethernet I/F Unit allows you to set up separate Class and
Net No.s for 2-Way Driver applications (Pro-Server, GP-Web and others)
and the PLC. When doing this, data transfer with the PLC is performed through
the optional Ethernet I/F Unit.
For cable connections, refer to the user's manual for each optional unit.
For the GP2000 and GLC2000 series units, however, refer to the User
Manual for the main unit.

HIDIC H Series Ethernet Protocol Limitations
When conecting your GP/GLC unit using the HIDIC H Ethernet Protocol to an
HIDIC H Series unit or a W eb Controller, the following limitations apply .
Device Address and Node Number Limitations
When a device address’s size is lar ger than 1024 (1K) or a different Node Number
set, the number of available device addresses will vary . The GP uses internal records
that are used to set the device addresses. These records are limited to 64. For
example, when the WR0 device address is set, a single record is used in the GP.
For detailed examples, refer to the following chart.
Ex1.) Number of records used when designating tag setting numbers.
Remaining
Setting
No.
10 3 WR2049 57

Number
1 1 WR0 63 Uses one record
2 1 WR1024 62 Uses one record
3 2 WR0 61 Uses one record
4 2 W R1024 60 Uses one record
51WM0 60
6 1 WM1024 60
7 1 W R2048 59 Uses one record
8 2 W R2048 58 Uses one record
9 3 W R2048 57 Uses one record

Number of
records in GP-
PRO/PBIII
Note
Since the Node Number and address
range already exist as setti ng No.1, no
records will be used.
Since the Node Number and address
range already exist as setti ng No.2, no
records will be used.
Since the Node Number and address
range already exist as setti ng No.9, no
records will be used.
When the total number of Node Number and Device Addresses exceeds
1024, GP internal records are used. However, if the Node Number and
Device Address are the same type, no record will be used, even if the device
types are different.
Ex2.) When setting tags from WR0000 to WR4000 in W ord Internal Output, since
one record is used for every 1024 addresses, a total of 16 records will be
used.
16384(0x4000)/1024=16
Therefore, when setting the same number of tags for each node, settings for a
total of four nodes can be set.
64/16=4
When the number of records is over 65, the following error message will
appear on GP-PRO/PBIII for Windows.
“Address entry limit reached. No more can be entered.”
