8.1.2 Allocation of G2 I/O Module Data to Common Memory
When FL654A operates by "TOOL specification", FL654A subordinate's G2 I/O module data is
allocated to FL-net common memory as follows.
(1) Input module data can be allocated freely to FL654A talker area by each input module. FL654A
talker area can be allocated in both area1 and area2 in FL-net common memory.
(2) Output module data can be allocated freely to the areas other than FL654A talker area by each
output module.
Table 8-1 Difference of TOOL specification and AUTO / LOCK specification
Item AUTO / LOCK specification TOOL specification
Input module data
Allocation Input module data is allocated from
the head of talker block in the former
stuff.
Talker block head address is
specified with rotary switch
(TBH,TBL). Input module data can be allocated
freely to FL654A talker area by each
input module.
(Talker block setting of nV-Tool is
used.)
Output module data
Allocation Output module data is allocated
from the head of listener block in the
former stuff.
Listener block head address is
specified with rotary switch
(LBH,LBL). Output module data can be allocated
freely to the areas other than FL654A
talker area.
(Talker block setting of nV-Tool is
used.)
Send data allocation
area
(Talker block) Send data allocation area can set
one consecutive area to either of
FL-net common memory area1 or
area2 at the same time.
Rotary switch (TBH,TBL) is not used.
FL654A talker area becomes send
data allocation area.
One consecutive
send data
allocation area can be set
respectively of common memory
area1 and area2.
Receive data
allocation area
(Listener block) Receive data allocation area can set
one consecutive area to either of
common memory area 1 or area 2 at
the same time.
Rotary switch (LBH,LBL) is not used.
Because data in FL-net common
memory other than FL654A talker
area can be specified for receive
data allocation area.
