• Is the transmission area of the remote module set correctly?
If the transmission area is set incorrectly, set it correctly. If the number of words to be sent is
set to 0, no data will be sent.
• Are the set module No. and CPL No. correct?
Check whether the set module No. and CPL No. are correct. Module No. setting and CPL No.
setting depend on the number of modules connected (see Section 5.2). If the set value is
duplicated, data will be sent incorrectly.
Data is not sent to the remote module.
• Is the key switch of the local module set to RUN?
If the key switch is not set to RUN, no memory transfer will take place.
• Is the transmission area of the local module set correctly?
If the transmission area is set incorrectly, set it correctly. If the number of words to be sent is
set to 0, no data will be sent.
• Are the set module No. and CPL No. correct?
Check whether the set module No. and CPL No. are correct. Module No. setting and CPL No.
setting depend on the number of the modules connected (see Section 5.2). If the set value is
duplicated, data will be sent incorrectly.
Transfer area data is lost.
• Is the transmission area of the module currently sending data set correctly?
If the transmission area is set incorrectly, set it correctly.
• Is a transmission area duplicated in several modules?
If the transmission area is duplicated, data in the area will be lost.
• Was the transfer area rewritten by the user program?
If possible, stop the user program and check whether the transfer area was rewritten.
The sent data was zeroized.
• Is the module currently sending data stopped (power failure)?
If CLEAR is selected, the content of the transfer area is zeroized when data transmission is
suspended.
• Is the key switch of the module currently sending data set to STOP?
If the key switch is set to STOP, no data will be sent from the transfer area. If CLEAR is
selected in hold/clear setting, the transfer area will be zeroized.
