Yaskawa 120 Series I/O Modules - Manual (Page 114)

3 Digital I/O Specifications
3.4.2 32-point Input Modules
3-84
b) Input Data Type
If an input register is set as the I/O reference number, data input can be set to binary
(BIN) or BCD. The MEMOSOFT is set by default to “BIN.”
c) Service Scan: Normal/High-speed
Two types of service scans are available: normal and high-speed. A service scan
is recommended when using the high-speed segment function. The I/O module is
activated before the ladder decoding of the high-speed segments. The I/Os that are
processed in synchronization with the high-speed scan are called High-speed Seg-
ment I/Os. The MEMOSOFT is set by default to “NORMAL.”
3.4.2 32-point Input Modules
1) Purpose of I/O Allocation
The relationship between I/O signals and I/O references must be defined so that the
CPU Module can input signals from input devices and output signals to output
devices. The following settings are necessary to define this relationship for Digital
Input Modules.
• Module Type
• I/O Reference Numbers
• I/O Data Format
Setting these items is performed in a process called I/O allocation. I/O allocation is
performed using the MEMOSOFT and the settings are recorded in the I/O allocation
tables stored in memory in the CPU Module.
Refer to the following manuals for specific setting procedures.
• MEOCON GL120, GL130 MEMOSOFT for P120 Programming Panel User’s
Manual (Manual No. SIEZ-C825-60.7), Chapter 7 Setting System Configuration.
• MEMOCON GL120, GL130 MEMOSOFT for DOS User’s Manual (Manual No.
SIEZ-C825-60.10), Chapter 7 Setting System Configuration.
• MEMOCON GL120, GL130 MEMOSOFT for Windows User’s Manual (Manual
No. SIEZ-C825-60.25), Chapter 6 Setting the Module Configuration.
2) Module Type Setting
The type of Input Module mounted in the slot is set as the module type. Only the last
11 alphanumeric characters of the model number are necessary. For example
120DDI35400 is the Module type for the JAMSC-120DDI35400.
