Appendix 8 Buffer Memory
893
A
*1 This memory is used by the system when the SIL2 function module or safety function module is executing functions.
*2 The safety function module with firmware version "11" or later supports this buffer memory area.
Un\G113 to Un\G143 Detailed information 2 • Detailed information 2 corresponding to the error code (Un\G0) is stored.
• The stored information contains the following six types.
0: N/A
2: Drive number and file name
3: Annunciator number
4: Parameter information
5: System configuration information
25: Process control instruction processing information
29: Other station error information (CC-Link IE Field)
• The type of detailed information 1 can be obtained using Un\G112. (The bit patterns for
values in the "Detailed information 2 information category code" stored in Un\G112
correspond to those in SD113 to SD143.) (

Un\G150 Program memory writing • b0: This relay switches to on when a write error is detected during write operation to the
program memory. This relay switches to off when the write instruction is issued.
• b1: This relay is on when the write process to the program memory is in progress. The
relay is switched to off when the write process is completed.
• b2: This relay switches to on when the number of program memory rewriting operations
reaches 100000. (The module must be replaced.)
Un\G152 Program memory write (transfer)
status This register displays the write (transfer) status to the program memory with a percentage
(0 to 100%). The initial value is "0". Upon completion of writing, this register is set to "100".
It is set to "0" at the time when the write command is issued.
Un\G153 to Un\G154 Program memory write count index • This register indicates the index value for the number of write operations to the program
memory up to now (stored as a 32-bit BIN value). However, the number of write
operations is not equal to the index value.
• When the index value exceeds 100000, an error is generated (the index value continues
to be counted even when it exceeds 100000). If the index value exceeds 100000, the
module must be replaced.
Un\G155 Data memory writing • b0: This relay switches to on when a write error is detected during write operation to the
data memory. This relay switches to off when the write instruction is issued.
• b1: This relay is on when the write process to the data memory is in progress. The relay
is switched to off when the write process is completed.
• b2: This relay switches to on when the number of data memory rewriting operations
reaches 100000. (The module must be replaced.)
Un\G157 Data memory write (transfer) status This register displays write (transfer) status to the data memory with a percentage. (0 to
100%). The initial value is "0". Upon completion of writing, this register is set to "100". It is
set to "0" at the time when the write command is issued.
Un\G158 to Un\G159 Index for the number of data memory
write operations • This register indicates the index value for the number of write operations to the data
memory up to now (stored as a 32-bit BIN value). However, the number of write
operations is not equal to the index value.
• When the index value exceeds 100000, an error is generated (the index value continues
to be counted even when it exceeds 100000). If the index value exceeds 100000, the
module must be replaced.
Un\G160 System memory writing • b0: This relay switches to on when a write error is detected during write operation to the
system memory (Flash ROM)
*1
. This relay switches to off when the write instruction is
issued.
• b1: This relay switches to on when the write process to the system memory (Flash
ROM)
*1
is in progress, and switches to off when the write process is complete.
• b2: This relay switches to on when the number of system memory (Flash ROM)
*1
rewrite
operations reaches 100000. (The SIL2 function module or safety function module must
be replaced.)
Un\G163 to Un\G164 Index for the number of system
memory write operations • This register indicates the index value for the number of write operations to the system
memory (Flash ROM)
*1
up to now. (stored as a 32-bit BIN value). However, the number
of write operations is not equal to the index value.
• When the index value exceeds 100000, an error is generated (the index value continues
to be counted even when it exceeds 100000). If the index value exceeds 100000, the
module must be replaced.
