Title Differences from the Hitachi control computer-H series
Applicable models All models
Question What are the differences from the Hitachi control computer-H series?
Answer Hitachi's current PLCs come in two lines. The H series of PLCs is based on ladder control. The S10mini is a small controller with computing capability that enables simultaneous execution of ladder, HI-FLOW and C language.
Title How to connect a graphic display
Applicable models All models
Question The S10/2α has high-level link port built into its CPU. However, the S10mini has no such port. How should the graphic display be connected?
Answer The RS-232C or RS-422 module of the S10mini can be used in high-level link mode (configured with a rotary switch) to enable the connection of a display connectable with the S10α series. Moreover, the S10α series was designed to be connected to an RS-232C port via the RS-422 port or RS-422/RS-232C converter of the display, while the S1omini must be directly connected to the RS-232C or RS-422 port of the display. If there is a choice of model between the 2α and 4α in the configuration on the connectable display side, select 2α. For the supportability of the S10α series, consult the respective display manufacturer.
Title Compatibility of applications with conventional models
Applicable models All models
Question Is there application compatibility with conventional models?
Answer All models of the 2α series are compatible in ladder, HI-FLOW user programs, and 2αE, 2αH and 2αHf C language user programs. For others, compatibility can be ensured by conversion (4α ladder) or recompilation (C language for 2α) or something similar. In the case of 2αE, 2αH and 2αHf, files backed up with a collective save/load system (model S-7890-09J) can be restored on the S10mini (provided that the optional module and expanded memory capacity are be the same).
Title Compatibility of remote I/O
Applicable models All models
Question Is remote I/O compatible with conventional models (S10α series)?
Answer It is fully compatible. The S10mini can be added to the CPU of the S10α via remote I/O. Moreover, the CPU of the S10mini can be provided with an additional I/O unit of S10α via remote I/O. The I/O unit of S10mini can be mixed with the I/O unit of s10α on the same remote I/O line.
Title Ladder execution cycle and I/O refreshment synchronization
Applicable models All models
Question Does the system support the ladder execution cycle and I/O refreshment synchronization?
Answer The standard remote I/O remote is not synchronized. For synchronous use, use the J.NET (OPCN-1) module.
Title Connection of PSEα
Applicable models All models
Question Is the PSEα connectable?
Answer It is connectable. However, there are some limitations (such as lack of support for optional modules with only the S10mini). Connection with the S10mini requires a special-purpose interface cable (model S10m-IFH3-P).
Title Type of supporting OS for the Windows version programming tools
Applicable models All models
Question The Windows version programming tools are compatible with what OS version?
Answer The system is Windows 95/98/2000/XP for DOS/V computers. It does not support Windows 95/98/2000/XP for NEC (PC-98).
Title Compatibility of DOS version programming tools with Windows version programming tools
Applicable models All models
Question Are programs prepared with a DOS version programming tool (PC-9801 series) usable on a Windows version programming tool?
Answer Methods vary with languages, but can be used.
[ Ladder diagram ]
You can move easily if you load the system into the CPU by using the DOS version ladder diagram system and save it with the Windows version ladder diagram system. Moreover, files saved with a DOS version programming tool can be read as is by using a Windows version programming tool. I/O comments require a separate comment converter (model S-7890-19J).
[ HI-FLOW ]
You can move easily if you load the system into the CPU by using the DOS version HI-FLOW system and save it with the Windows version HI-FLOW system. Moreover, files saved with a DOS version HI-FLOW system can be read by using a Windows version HI-FLOW system.
[ C language ]
Copy the source file (text file) prepared on PC-9801 onto a DOS/V cpmputer, make the system settings (such as site generation and allocation) by using Windows version RPDP, and then recompile.
Title Compatibility of PSEα with Windows version programming tools
Applicable models All models
Question Are programs prepared on PSEα usable on a Windows version programming tool?
Answer In the case of a ladder diagram, you can move easily if you load the system into the CPU by using the PSEα and save it by using the Windows version ladder diagram system. If you wish to use comments on the ladder diagram, HI-FLOW or a C language program, you need a PC-9801. For the details of the method, consult our technical support.
