ros7.1rc4 not work with importing a /system scheduler in general. http://forum.mikrotik.com/t/v7-1rc4-development-is-released/152002/168 SUP-61613
WorkARound for RouterOS 7.1rc4
Create a system scheduler with interval=00:01:00 and code:
#Script WatchDog for script name:
local ScriptName lteLogger2
local ScriptRuningInstances [:len [system script job find script=$ScriptName]]
if ( $ScriptRuningInstances = 0) do={/system script run $ScriptName};
if ( $ScriptRuningInstances = 1) do={};
if ( $ScriptRuningInstances >= 2) do={system script job remove [find script=$ScriptName]};
Next is to run this code in terminal who create you a final script.
/system script
remove [find name=lteLogger2]
add name=lteLogger2 source="#:local watchItems pin-status,functionality,registra\
tion-status,current-cellid,enb-id,sector-id,phy-cellid,access-technology,primary-band,ca-band,rssi\r\
\n:local watchItems current-cellid,enb-id,primary-band,ca-band\r\
\n:local watchFreq 3s\r\
\n:local lteInfo\r\
\n:local prevLteInfo ({})\r\
\n:while (true) do={\r\
\n\t:do {:set lteInfo [/interface lte monitor lte1 once as-value]} on-error={}\r\
\n\t:foreach m in=\$watchItems do={\r\
\n\t\t:if ((\$lteInfo->\$m)!=(\$prevLteInfo->\$m)) do={\r\
\n\t\t\t:put (\$m.\": \".(\$prevLteInfo->\$m).\" -> \".(\$lteInfo->\$m))\r\
\n\t\t\t:log warning (\$m.\": \".(\$prevLteInfo->\$m).\" -> \".(\$lteInfo->\$m))\r\
\n\t\t\tlocal mpprev (\$prevLteInfo->\$m);\r\
\n\t\t\tlocal mpnext (\$lteInfo->\$m);\r\
\n\t\t\t:set (\$prevLteInfo->\$m) (\$lteInfo->\$m)\r\
\n\t\t\t}\r\
\n\t\t}\r\
\n\t:delay \$watchFreq\r\
\n\t}\r\
